Ciara's no stranger to sharing sexy snapshots on social media, and they're something of an issue for us ... because we just can't leave 'em alone!

Ariana Grande just confirmed her fans' worst fear -- she nearly stopped making music ... until "Wicked" changed her mind!

That's right -- AG confirmed "Wicked" helped her find her inspiration to hit the studio again after secretly deciding she was never going to "make an album ever again," the pop star revealed on Friday's "Shut Up Evan" podcast.

As you know, the pop star took a hiatus from releasing music as she fully dove into her role of Glinda in the movie adaptation of the popular musical ... and fans were throwing red flags all over the place. But, she settled their fears when she released 2024's "Eternal Sunshine."

It's going to be a minute before fans see Nelly Furtado performing on stage ... 'cause she says she's stepping away for the "foreseeable future."

The "Maneater" hitmaker announced the shocking news on Instagram Friday, telling fans while she's so thankful for her journey ever since her first album "Whoa, Nelly!" was released 25 years ago ... she feels it's time to "step away" to focus on "other creative and personal endeavors."

She didn't reveal what's up next for her ... but confirmed she will always be writing music, even if that doesn't mean performing it.

Carly Rae Jepsen and her man Cole M.G.N. are ready to have a "Good Time" together forever ... 'cause they tied the knot in an intimiate New York City ceremony.

CRJ wore a pretty traditional wedding gown with the white veil standing out against her auburn hair in one photo while she laid a smooch on her husband.

Talk about the ultimate buzz kill ... Hilary Duff was crying over spilled couture ... 'cause her designer bag took a soaking before she even got her first sip of coffee!

Hilary hopped on IG to show the crime scene ... her Balenciaga’s contents all stained latte-brown, basically turned into a sad to-go cup … with the guilty, empty coffee cup sitting right next to it.

Hilary said the whole disaster struck before she even got her first sip ... and yeah, that’s definitely a latte to deal with before 9 AM!

Britney Spears brought the "Circus" to an L.A. eatery Wednesday night ... exciting patrons of the place when she walked in for food and drinks with her friends.

The singer-songwriter hit up RED O in Thousand Oaks -- a suburb of L.A. about 15 miles from the city -- standing out in a bright yellow blouse which bared her shoulders, and a fashionable black hat.

Eyewitnesses tell TMZ Britney was in good spirits ... complimenting others on their outfits and even taking pics at the bar with a few of her fans.

Grimes' tattoo is a bold move -- one ya gotta make to shock people with tattoos these days ... so says a celebrity tat artist who has been around the block a time or two.

We caught up with Mark Mahoney -- a pro who's been practicing his craft for nearly five decades -- and we showed him Grimes' new controversial tattoo ... which is basically a big red circle that looks almost like a scar around her eye.

Mark -- who has tattooed stars like David Beckham, Lady Gaga and more -- says even a small tattoo on the arm used to shock old ladies at the store ... but, in today's culture, shock from tattoo is reserved for the wild and crazier ideas -- which he thinks might be the reason Grimes decided on this design.

Romance rumors have been swirling around Keith Urban and his guitarist, Maggie Baugh ... but her friend, singer Alexandra Kay, wants to put a stop to it.

Some have speculated Maggie has been dating Keith following his split from Nicole Kidman ... even suggesting she may have had some involvement in their divorce. But in an interview with "Taste Of Country" on YouTube, Alexandra insisted the rumors are "absolutely not true."

She said, "I've met her boyfriend. She's very happy and she has nothing to do with that whole relationship."

Paul McCartney left the 'Strawberry Fields' behind for a different idyllic location -- an overpass in Tulsa, Oklahoma ... no, we aren't kidding.

The singer-songwriter shared a video on TikTok Thursday of himself in the Sooner State on the bank of a river ... sitting on a slope set just a bit down from a huge highway overpass.

PM says he's got a beautiful view of the "pretty big, groovy" Arkansas River ... and, he flips the camera to show his followers the view he's looking at.

Could Tyla be any cuter??? The singer-songwriter looked insanely hot in a new video posted Friday.

The 23-year-old Grammy winner stunned in a skimpy polka-dot bikini reminiscent of a maid's outfit, strutting and twisting on a soundstage to her new song, "Chanel."

She wrote, "CHANEL OUT EVERYWHEREEEE" promoting her latest banger.

Even celebs get starstruck ... Ariana Grande practically lost all chill when the one and only Sarah Jessica Parker acknowledged her existence!

On the "Shut Up Evan" podcast, the "Wicked" star got a surprise voicemail from none other than the "Sex and The City" queen herself. But before Ariana could even answer SJP’s burning question, she was already tearing up like a total fangirl.

Ariana was so shook, she blurted out to Evan, "She knows who I am!" ... then pulled it together just enough to dive into how fame looks now versus what she dreamed it’d be as a kid.

Gigi Hadid got cuffed by none other than Sabrina Carpenter ... and let’s just say, the pop star was burning up over the supermodel.

Check out the clip -- Sabrina had her sights set on Gigi during her "Short n' Sweet" tour in Pittsburgh Thursday evening, playfully asking the model in the crowd where she's from ... and when Gigi said Bucks County, Sabrina fired back with a flirty, "Wow, maybe we're soulmates!"

Sabrina confessed she was "hot and flustered" over Gigi before slapping her with some furry pink handcuffs ... bold doesn’t even cover it!

Bad Bunny just keeps racking up the wins -- and probably driving his haters nuts -- after snagging the "Best Artist of the 21st Century" award at the Latin Billboard Awards.

Check out his big moment ... Bad Bunny hit the stage Thursday as legendary Puerto Rican actress Rita Moreno handed him his milestone trophy after praising him for being an artist with immense "strength and passion."

As for the "DtMF" hitmaker, he agreed he's worked hard to reach this pinnacle point in his career -- but doesn't forget to mention his team hustling there right alongside him, or the other Latin music artists also driving the genre to the mainstream.

Electric duo LMFAO -- made up of Redfoo and Sky Blu -- stormed the music charts with their hit songs "Party Rock Anthem" and "Sexy And I Know It" back in 2009.

In 2012, they went their separate ways to focus on solo careers -- and have yet to reunite for a PARTY!

"Party rock is in the house tonight. Everybody just have a good time. And we gon' make you lose your mind. We just wanna see you, Shake that!"

Bon Jovi fans livin' on the prayer that Richie Sambora will tour with the band next year are going to be crushed ... 'cause TMZ has learned a full reunion isn't in the group's future.

Here's the deal ... after Bon Jovi announced their "Forever" tour scheduled for next summer, fans flocked to social media, totally convinced the group would bring Richie back for a show or two.

However, sources with direct knowledge tell us fans who are trying to "Never Say Goodbye" to Sambora are delusional ... because we're told such a reunion isn't going to happen. Ever.

Ace Frehley did the impossible ... bringing his former bandmates back together to celebrate him at a private funeral held earlier this week in the Bronx.

Eddie Trunk -- a well-known radio DJ and close friend of the band for many years -- shared a summary of the intimate affair ... as well as a photo of what looks like Ace's grave marker.

The plaque has Ace's full name written out with the dates of his birth and death sitting above the Bible verse John 14: 1-3, 27 ... which reads, in part, "Let not your heart be troubled, neither let it be afraid" ... so, it sounds like Ace is trying to provide comfort even though he's gone now.
