Taylor Swift certainly had love on her mind at Jack Antonoff's wedding, but while that was going down, her ex-boyfriend Matty Healy was on the other coast ... laser-focused on music.

We've learned The 1975 frontman was browsing around a music shop, Norman's Rare Guitars, in Tarzana, CA on Saturday ... the same day Taylor was watching Jack and actress Margaret Qualley tie the knot.

The musician swung by the store with his tour manager, ultimately buying a guitar -- unclear how much dough he put down for it, but it looks like a pretty sweet Fender 6-string.

While Matty was shopping on the west coast, Taylor was at the big ceremony on the Jersey Shore ... where, as we reported, droves of Swifties flooded the main street on Long Beach Island to get a glimpse of the singer.

You'll recall, Matty and Taylor were briefly an item, spotted hanging out quite a bit in May, and he even snuck into her NYC pad ... but sources told us Taylor was "single" again in June, although it's unclear why they called things off.

Taylor Swift is no stranger to the fact she draws a crowd ... making sure her team met with local cops before Jack Antonoff's wedding to prep for the crush of fans showing up to catch a glimpse of their favorite singer.

Beach Haven Police Chief James Markoski tells TMZ ... security for the singer and her producer pal met with the department 2 weeks before the weekend wedding, and Jack's wedding planner paid for 3 additional officers to be on duty during the event.

We're told 2 viewing areas were set up for fans outside the Long Beach Island bash in New Jersey -- cops also shut down 3 intersections to prevent cars from getting near the folks in the designated areas, hoping to get a peek of the celebs.

For those unaware, a fishing competition and a block party were going down in the area at the same time ... but we're told there were no arrests, tickets, or major injuries that went down during all the ruckus.

As for the swarm of fans, Markoski tells us they stuck around for nearly 12 hours, showing up around 2 PM and getting out of there after Taylor finally left the wedding around 1:30 AM.

Britney Spears is working fast to put Sam Asghari behind her … surrounding herself with a ton of shirtless men, all vying for Brit's attention.

The pop star posted the racy video on Instagram, showing one guy trying to lick Brit’s leg all the way up to her thigh. You can hear the cameraman order him to, “Start at the boot, bro..”

The video then jumps to Brit being hoisted up by 5 bare-chested men around a pool. Brit seems more than satisfied, punctuating the moment with “Okay cool!"

Brit wrote in her caption, 'When you go to meet up with a so called "friend" and drive an hour for chicken! Then you have to wait in the car and need to use the bathroom.”

She continued. “So what does a b**** like me do?! I put my green dress on and show up at my friends! I invited my [favorite] boys over and played all night!”

On Sunday, Britney also posted a topless video on Instagram. Of course, this all followed last week’s drama when Sam Asghari filed for divorce from Britney, citing irreconcilable differences.

Since then, it’s been all downhill for the exes, who are no longer talking to one another.

We covered the story on the latest episode of The TMZ Podcast, available on all podcast platforms.

Britney Spears fans eager to get their hands on her memoir won't get a glimpse into the downfall of her marriage with Sam Asghari ... TMZ has learned.

It was back in July when Britney announced her book, "The Woman in Me" had finally gotten a release date of October 24. Obviously, fans were thrilled ... but there's been a huge development in Britney's life since that announcement.

Sources with direct knowledge tell TMZ there won't be any changes made to the memoir to reflect Britney's divorce ... we're told the book will be released as is.

In fact, our sources say 2 weeks ago, Britney gave her final sign-off on the book, meaning she had no right to demand any further changes.

What's more, our sources say since the news of Britney's divorce broke, presales for "The Woman in Me" have only increased ... though it's likely those fans don't realize the divorce drama won't be included.

We've spoken with someone directly involved with the book who tells us Sam is featured in it, but their relationship is not the main crux of her story -- it's more about Britney's early life, career and journey out of her conservatorship.

It's been a couple days since Kid Rock was spotted sipping a Bud Light -- and the reactions across Twitter have been just as unhinged as you'd expect ... with people weighing in on both sides.

For starters, accounts that usually push conservative views seem to feel betrayed in a sense ... some writing, "TREASON" another wrote, "I am STRONGLY against CANCEL CULTURE but I am calling for a boycott of all Kid Rock products until further notice."

Others simply seem to be in disbelief, "C'mon Kid Rock, what are we doing?"

However, some on the right are still sticking with their guy, announcing, "I will ALWAYS stand with Kid Rock! If you’ve already had many non-woke beers, it is easy to be tricked into drinking a woke Bud Light by accident. Give Kid a break. He’s fighting hard for our freedom!"

Of course, the images have also been met with plenty of humor and memes as well, one account writing, "Damn, never thought I’d have to give Kid Rock the Bud Light treatment but here we are. Just shot up all my Kid Rock vinyl and CDs. I loved Kid Rock, but I hope Kid Woke goes broke."

TMZ broke the story, the Trump fanatic was spotted drinking a Bud Light at a concert in Nashville last week.

The scenario seemed almost impossible a few months back when KR uploaded himself shooting up a bunch of cases of the beer, exclaiming, "F*** Bud Light and f*** Anheuser Busch" after trans influencer Dylan Mulvaney published an ad-spot with the company.

Jack Antonoff and Margaret Qualley are now officially husband and wife, and the newlyweds said their “I Do’s” during a star-studded affair, with Taylor Swift looking on.

The couple tied the knot Saturday at Parker’s Garage in Long Beach Island, New Jersey — and in addition to Taylor, the celebrity guest list included Lana Del Rey, Channing Tatum, Zoe Kravitz and Cara Delevingne.

Everyone, of course, was dressed to the nines, especially the bride and groom. Jack looked spiffy in his black tux and Margaret looked even more amazing in her fancy white gown.

Taylor, Jack’s longtime friend and music collaborator, was equally as glamorous in her light blue gown. The others weren’t too far behind in their snazzy get-ups.

Margaret’s mom, actress Andie MacDowell, made a grand entrance with her stunning head of hair, consisting of long gray curly locks.

The wedding ceremony was private and low key unlike the night before when Taylor showed up at the rehearsal dinner nearby and a large group of her fans went absolutely nuts, creating a chaotic scene on the streets outside the venue.

Taylor Swift not only turns heads, she shuts down roads!!!

T.S. hit up Jack Antonoff's rehearsal dinner Friday night, and so many fans found out ahead, they caused a major New Jersey road to be impassable.

Antonoff, Taylor's frequent collaborator, is marrying actress Margret Qualley, and they celebrated at the Black Whale restaurant in Beach Haven.

Cops apparently got the memo Taylor was going to show, so they were out in force to control the hundreds of fans who wanted to catch a glimpse of their hero.

Swift has been performing regular 3 hour shows around the country, but she still has the energy to party well into the night,

Christina Aguilera traded in her walking shoes for a set o' wheels at Disneyland ... celebrating her daughter's birthday while also giving her feet and legs a rest.

The singer -- and former "Mickey Mouse Club" member -- took to the Happiest Place on Earth Wednesday, donning matching tie-dye shirts with her partner, Matthew Rutler, and some pals for Summer Rain's 9th birthday.

Her group was escorted by a private tour guide, getting front-of-the-line access to rides like Alice in Wonderland ... but while the rest of her crew was walking around the park, Christina remained seated on a motorized scooter.

Disney normally rents the transports out to guests, and a source close to Christina tells us the singer needed it because she's currently nursing a minor knee injury.

It's nothing too serious, but we're told she's trying to rest it to make sure it doesn't get worse.

The Killers are apologizing to their fans after getting pelted with boos at a recent concert in the country of Georgia for bringing a Russian fan onstage and calling him their "brother."

The rock band, led by singer Brandon Flowers, invited a fan up onstage at their Shekvetili gig Tuesday to play the drums -- a tradition the group's been doing for a while. This fan, however, claimed he was from Russia ... something the Georgian crowd wasn't thrilled with.

Brandon and co. got a swarm of negative responses instantly, prompting him to suggest the man was the country's brother -- which set them off even more. After more booing, he asked if he wasn't their brother, being from America ... and got more boos.

The crowd got pretty pissed, and many folks in the crowd reportedly left in protest ... and the band offered up an apology after the rough show, saying, "Good people of Georgia, it was never our intention to offend anyone!"

Responding to the "brother" comment, they add, "We recognize that a comment, meant to suggest that all of The Killers' audience and fans are 'brothers and sisters,' could be misconstrued. We did not mean to upset anyone and we apologize."

Tori Kelly must be feeling a whole lot better after her major health scare … because she’s hitting the road for a nationwide tour and in Canada.

The Grammy-winning singer announced her plans for "The Take Control Tour" on Instagram Tuesday, writing, "It’s been too long." She gave a list of tour dates, beginning on September 10 in Toronto, Ontario, before moving on to a number of American cities, including L.A. and NYC.

Fans can DM Tori to snag presale tickets at 9 AM today -- others can purchase general admission tickets Thursday through her website.

This is great news for Tori, who was hospitalized with serious blood clots last month. TMZ broke the story … Tori was having dinner with friends at a downtown L.A. restaurant when she passed out and was rushed to the hospital.

Colombian singer Manuel Turizo is makin' moves after his recent collab with Shakira ... because he's now working with the Mexican-American mega group, Grupo Frontera.

TMZ's learned Manuel and the popular band are joining forces for a new song and music video, called "De Lunes a Lunes"  -- something they're planning on officially announcing in the coming weeks.

TMZ has obtained some shots of Manuel and Grupo Frontera on set in Miami last week shooting the music vid ... and they all seemed to be gettin' along pretty damn well.

The guys came together because they're big fans of each other and wanted to collab on a new sound, combining each of their styles.

As you know, Manuel's track with Shakira, "Copa Vacía," has blown up since dropping in June, and he's got a lot going for him right now.

He was nominated for the Rolling Stone En Español Awards Monday, and he closed out La casa de los famosos -- the Spanish language version of "Celebrity Big Brother" -- with a performance.

Katharine McPhee and David Foster's son's nanny died after an elderly woman at a Toyota dealership ran her over with an SUV.

Our sources say the nanny, Yadira Calito, is the woman who died last week in an incident at a San Fernando Valley car dealership.

The fatal accident happened Wednesday morning at Hamer Toyota when an 84-year-old woman behind the wheel of a Toyota RAV4 crashed into the customer reception area.

Kat's nanny was pinned under the SUV and dragged for about 20 feet before eventually being freed from under the car. She was rushed to a hospital in critical condition, and later pronounced dead.

Police say the elderly driver was taking her car in for service when she hit the gas instead of the brakes ... sending her car from the service bay driveway into the customer reception area. The driver has not been arrested.

Two men working at the Toyota dealership were also injured in the crash ... but both are expected to make full recoveries.

Selena Gomez and Francia Raisa's relationship is officially out of the gutter -- that much is clear -- but we can't swear that's also true for their bowling game, which they worked on together.

Selena and her one-time BFF/kidney donor hit up a Studio City bowling alley Monday night, and even hopped in the same car after their time on the lanes with some other pals.

It's hard to say if their friendship is back to what it once was, but as we reported, it's been moving in that direction -- they were dining out together just a few days before taking on the 10 pins.

Selena and Francia hit up celeb hot spot Giorgio Baldi Friday night in Santa Monica, both looking as stunning as ever while getting in the same ride.

You'll recall, they've had an up-and-down relationship since the transplant, but Francia recently claimed there's no more bad blood ... after Selena wished Francia a happy birthday last month.

Beyoncé is setting the record straight on her feelings toward Lizzo -- not only is she back to name-dropping the artist in song, she also singled her out with a loving shout-out.

Bey was bringing the house down, per usual, Monday night at Mercedes-Benz Stadium in ATL, and performed "Break My Soul (The Queens Remix)," which supports her fellow female artists -- including Lizzo -- by shouting them out.

You may recall, Lizzo was notably absent from the song's callout section during a Beyoncé show earlier this month, but she was back on the lineup a couple of days later. Bey took things a step further this time, though -- saying, "I love you, Lizzo!"

The crowd certainly took that as a sign -- one fan in the crowd even responded, "OK!"

As we reported, Beyoncé ditched Lizzo's name at a Massachusetts show on August 1 ... coming directly after the "About Damn Time" singer was slapped with a lawsuit from 3 of her former dancers, claiming she created a hostile work environment with alleged sexual harassment and fat-shaming, among other things.

Lizzo, for what it's worth, has denied the allegations against her ... and it looks like Beyoncé's got Lizzo's back, and then some.

Adele's got a habit of tearing up onstage while singing her love songs, but her latest sob sesh is for a gender reveal ... not hers, but for a couple of her fans in Vegas.

Chris Dare and his wife, Shantelle Lord, got the gender reveal party of a lifetime at Adele's residency show at Caesars Palace, getting the singer to answer the question: boy or girl?

Adele was filled with excitement from the get-go during the weekend, and eventually revealed the parents-to-be are having a baby boy -- which got the 3 of them, and the entire audience, jumping for joy.

After wishing them well, Adele breaks down in tears, apologizing to the crowd for getting emotional ... before jokingly asking Chris and Shantelle to do her next gender reveal "if and when" she gets pregnant again.

Mike Posner says the emotional pain he's dealing with now is all part of life's plan to teach him lessons in order to learn and grow and then pass his knowledge along to others.

The singer joined us Monday on "TMZ Live" and we asked him how things are going after he recently got brutally honest with one of our photogs ... saying he was embarking on a spiritual warpath to deal with some life challenges.

Mike says he's doing better now and his latest challenge helped him change and grow for the better ... just like a lot of the hurdles he's faced in life and in his career.

He tells us he's grateful for his life in general and all the highs he's experienced -- like Grammy nominations -- and, with that, he's also grateful for all the pain as well.

In Mike's case, there is another silver lining with life's hardships -- they can make for great music, as he points out ... art is a great outlet for sadness, depression, rage, anger and fear.

For Mike, life's teaching him what he needs to learn in order for him to teach others ... and he's got an opportunity coming up to do just that ... with a curated trip to Iceland.
