Breakups

Drew Barrymore is officially calling it quits on her marriage to Will Kopelman ... filing for divorce after 4 years of marriage.

Drew filed Friday in Manhattan according to the NY Daily News. The divorce is uncontested, meaning it should be pretty amicable, absent any squabbles over money or their 2 daughters -- ages 2 and 3.

The couple said back in April they were separating.

Lakers guards are turning over women like they do basketballs ... first Nick and Iggy, now D'Angelo Russell is on the market ... after a breakup with his superstar college athlete GF Niki Withers.

The couple scrubbed each other off all social media -- a telltale sign of trouble in paradise -- and sources close to the situation confirmed the two are, in fact, dunzo.

"D'Angelo and Niki talked about where the relationship was going and decided mutually to break up," one source tells us.

Unlike Nick & Iggy there's no bad blood between the two ... we're told the breakup was simply a case of two youngsters growing apart.

The relationship endured some tough times ... with Niki standing by DR when his infamous video of Swaggy made him the number one bro code violator in the history of sports.

Question is, now that both men are single ... might it be time to reignite the friendship over a few thots?

Was Iggy Azalea holding Nick Young's career back?

The NBA star certainly implied it Wednesday night at Shore Bar in L.A. -- when he implied he'll be better on the court now that his engagement is off.

Photog: "Think the single life will help keep your game tight this season?"

Nick: "Yeah, I'm back on track!"

Taylor Swift is swinging back ... calling BS on Calvin Harris' Twitter tirade in which he claims he was the architect behind the hit song, "This Is What You Came For."

Sources close to Taylor tell TMZ ... Calvin's intentionally downplaying her involvement, essentially saying he did all the music. But Taylor says not only did she write the lyrics ... she also created the melody, and those 2 elements are the essence of any song.

Our Calvin sources concede Taylor indeed wrote the melody ... but his musical genius with beats, chords and instrumentals made the song a hit.

A Calvin source scoffs, "She's acting like he's only got one hit song. LOL."

Taylor Swift really is the creative brains behind Calvin Harris' monster hit "This is What You Came For," and their relationship fell apart because he disrespected her when the song was released ... this according to sources connected with Taylor.

It's a fascinating story. We've learned an early fan rumor about the song is true, but to a deeper extent than anyone suspected. During their relationship, Taylor wrote the song, sat down at a piano and did a demo into her iPhone. She sent it to Calvin, who loved it. They both went into a studio and did a full demo with Taylor on vocals and Calvin doing the beat.

They both knew the song would be a hit, but Taylor wrote it for Calvin and both agreed it was a bad idea to let the world know they collaborated as a couple ... it would overshadow the song.

So Taylor, who kept the publishing rights, used the pseudonym Nils Sjoberg on the credits.

Fast forward to April 29th. Calvin released the song with Rihanna and it became an instant hit. It's been at #1 or #2 on the Dance/Electronic chart for 9 weeks, and is #5 on the Billboard 100.

The problem in the relationship came the day the song was released. Calvin appeared on Ryan Seacrest's radio show and Ryan asked, "Will you do a collaboration with your girlfriend?" Calvin responded, "You know we haven't even spoken about it. I can't see it happening though."

We're told Taylor was hurt and felt Calvin took it too far.

It was a quick downward spiral from that point. One source called it "the breaking point in the relationship." The Met Gala was several days later, when Taylor danced with Tom Hiddleston.

BTW ... Taylor has the right to prohibit Calvin from performing the song, but she hasn't and doesn't plan to exercise that right. Ironically, Calvin once wrote a song with then-GF Rita Ora and when they broke up he yanked her right to perform it.

As for why the squad is talking now ... we're told they're sick of Calvin trashing Taylor and feel he should be thanking her for quietly giving him a smash hit.

We reached out to Taylor's rep. So far no word back.

Lamar Odom just filed his response to Khloe Kardashian's divorce petition ... and it shows the exes are lockstep when it comes to this breakup.

In the docs, obtained by TMZ Sports, Lamar lists the exact same date of separation as Khloe did -- December 13, 2013. Ditto for court's ability to award spousal support to the other. As we reported, our sources say they have a prenup.

They even agree each will pay for their own attorneys, a rarity in Hollywood divorces.

Nick Young's got a cold, hard fact for his baby mama -- Swaggy P's single and completely unattached, even though he knocked her up a second time.

Sources close to the NBA star tell TMZ Sports ... Nick and his ex, Keonna Green, are NOT back together. If you'll recall ... Keonna told US Weekly she wasn't apologizing "for being in love with a man who I have a lot of history with." It appears that's exactly where Nick wants to keep it -- in the history books.

We're told Nick's living it up in the single lane and wants to keep it that way so he can concentrate on the upcoming NBA season. Nick's living alone in the house he used to share with Iggy. Keonna's NOT living there.

As for Iggy'z one-finger salute the other day ... Nick's not trippin.

The song Calvin Harris wrote for John Newman -- which Calvin says chronicles a love triangle between him, Taylor Swift and her new BF Tom Hiddleston -- just dropped ... and it sure sounds like a play-by-play.

TMZ broke the story ... Calvin wrote the cheating song "Olé" from Tom's POV. But Taylor's camp's calling BS ... saying Calvin wrote the song long before she hooked up with Tom.

The lyrics we said would be in the song are there ... with Tom's famous 'Thor' character, Loki, kicking off the song -- "Low key you won't tell none of your friends about me."

And ...

-- "You've hidden my name in your phone so you can call me to tell me you've been going through hell. Left him alone and you booked in a hotel."

-- "I see online that you begun to be a good girl and take trips with your boyfriend. Being attentive, continue to pretend ..."

Sounds like a hit!

Iggy Azalea now thinks Nick Young can share the blame for their breakup ... with a particular type of person.

We got Iggy at LAX after her flight from Australia -- hours after her epic one finger salute -- and when she was asked what's next, she had a very interesting response.

Now we know what she's looking for in a man. It's also clear she's pissed about Nick's situation -- being a father -- and thinks that's ultimately what opened the door for that other situation. Y'know ... Keonna.

Calvin Harris was working on his so-called cheating song long before Taylor Swift hooked up with Tom Hiddleston ... according to several sources.

According to the sources, Taylor knew all about "Olé" because Calvin started writing it before Tom was in the picture. One source told us, "If Calvin claims he wasn't working on this before the Met Ball, he's lying."

The Met Ball in early May is a key moment in the breakup. You'll recall Calvin did not go to the gala with Taylor ... and she was seen dancing the night away with Hiddleston that night.

Here's the rub. In the song, Calvin wrote, "Low key you won't tell none of your friends about me." As you know, Tom famously play Loki in 'Thor.' Using the words "low key" would be a big coincidence.

Calvin Harris has beaten Taylor Swift to the punch, writing a cheating song ... about her.

The John Newman track is called "Olé," and it's written from Tom Hiddleston's POV. The lyrics make it clear ... Calvin believes Taylor had hooked up with Tom way before she broke up with him.

One lyric goes, "I see online that you begun to be a good girl and take trips with your boyfriend. Being attentive, continue to pretend ..."

If that wasn't clear enough, the song goes on ... "You've hidden my name in your phone so you can call me to tell me you've been going through hell. Left him alone and you booked in a hotel."

And, using Tom's famous 'Thor' character, Loki, the song goes on, "Low key you won't tell none of your friends about me."

Our Calvin sources say he has no animus towards Tom ... he feels he's under Taylor's spell, and the one who made the fateful decisions was her and her alone.

The pic below was taken in Mexico last week with Newman, the singer on the track. They shot the music video south of the border.

Iggy Azalea has a big 'ol message to Nick Young and the woman he knocked up -- EFF YOU BOTH!!

Iggy fired off the one finger salute -- which she clarified was directed at Nick and Keonna Green -- while at an airport in Australia on Wednesday ... hours after Keonna spilled her guts to US Weekly about her secret affair with the NBA star.

Iggy also claims Keonna's a liar -- saying Keonna is simply not telling the truth about an alleged attempt to contact Iggy to clue her in on the adultery.

Keonna -- who's 22 weeks preggo with Nick's child -- said she was hooking up with Nick since September ... 3 months after he proposed to Iggy.

Yeah, we kinda get why Iggy's pissed ...

Here's more proof Nick Young only cares about his balls ... he's already re-ignited his hoops training for next year's NBA season, and TMZ Sports has pics of the Lakers star puttin' in work.

Swaggy's fresh off being dumped by Iggy Azalea, and aired out by his baby mama Keonna Green, but it didn't stop him from hitting up the Sports Academy in Thousand Oaks, CA to work on his J.

Check out the pics -- SA is a MASSIVE training center and Nick seems to use every inch of it ... hitting the weights in addition to getting his shots up.

The multi-million dollar guitar famously owned by Kurt Cobain -- the last one he played before killing himself -- is at the center of Frances Bean Cobain's nasty divorce.

Frances' estranged hubby, Isaiah Silva, claims she gave him Kurt's Martin D-18E as a wedding present. It's the same instrument the Nirvana frontman famously strummed during his epic "MTV Unplugged" performance.

The acoustic-electric is something of a holy grail for Nirvana fans. For starters, only about 300 were made before Martin discontinued the model. Kurt, who was left-handed, had the bridge and nut replaced so he could play it upside down.

Frances denies giving Isaiah the guitar, and wants it back, with good reason. It was once insured for $1 million and experts now think it's worth several million bucks.

We got Courtney Love at LAX Tuesday, who squarely sided with her daughter, essentially saying Isaiah's a scammer.

"Airplane!" and 'The Naked Gun' writer/director David Zucker filed for divorce from his wife Danielle ... but he says all is still fine and dandy between the two.

David submitted the docs earlier this week but he tells us it was a long time coming ... the couple has been separated for nearly 10 years. That's not all ... David says he and Danielle live just a few houses away from each other and routinely have family meals with their two kids.

As for why they've finally decided to call it quits -- David says they both knew it was time to officially move on -- but they'll still keep a friendly relationship.

According to the divorce docs, David's asking for physical custody of their teenagers -- a boy and a girl -- but surely wants to share legal custody with Danielle.

Kevin McKidd -- who plays Dr. Owen Hunt on "Grey's Anatomy" -- is getting a real-life MD ... Marital Dissolution ... and the family band is probably a goner.

Kevin's wife, Jane McKidd, has filed for divorce just weeks before their 17th anniversary. It was apparent the marriage was coming to an end -- they separated back in October.

Jane is asking for joint custody of their teenage kids, and she wants spousal support.

As for the band ... it was very Partridge Family. Jane played bass, the kids played piano and drums ... it's unclear what Kevin did in the group.
