Celebrity Feuds

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."

Calvin Harris is taking the gloves off and lighting up Taylor Swift over his/her hit song, "This Is What You Came For."

Calvin reacted to TMZ's story -- that Taylor wrote the lyrics and recorded a demo of the song, which Calvin used to produce the final edit ... with Rihanna singing.

He started with a compliment, saying Taylor is an "Amazing lyric writer and she smashed it as usual." But then came his true feelings -- "I wrote the music, produced the song, arranged it and cut the vocals though. And initially she wanted it kept secret."

During the Twitter rant, he also said it was "hurtful" that Taylor and co. are trying to make him look bad -- and suggested she focus on her new relationship, instead of attacking him.

And then the coup de grace -- a reference to (and confirmation of) her most famous beef. Before him.

Somewhere Taylor Swift is writing a song.

12:00 PM PT -- Katy Perry just responded in epic fashion ... clearly showing where she stands on the situation.

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.

The wife of Tampa Bay Buccaneers star Brent Grimes ripped into the Dolphins for cutting him and got a little anti-Semitic while she was at it.

Miko Grimes -- who was arrested last year for headbutting a cop at a Dolphins game -- started bashing Dolphins owner Stephen Ross and GM Mike Tannenbaum ... who she clearly blames for Brent's demise in Miami.

She tweeted, "Gotta respect ross for keeping his jew buddies employed but did he not see how tannenbaum put the jets in the dumpster w/that sanchez deal?"

The backlash was immediate, although Miko insisted she wasn't being racist and said ... "Why would i want to offend "jewish" ppl?"

That's exactly what she did though. FOX Sports NFL insider Jay Glazer -- who's done MMA training with Brent -- jumped in the fray, pleading with Miko to "please SHUT THE F*** UP! Sincerely, the Jew buddy of ur husbands."

Miko's reply? "Suck my d***!"

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!

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 ...

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.

Iggy Azalea's legal team fired off a scorching letter to Nick Young's baby mama ... warning her that any mention of Iggy in her upcoming tell-all story will spell BIG trouble for her.

We broke the story ... Nick's baby mama, Keonna Green, shopped around and sold her story as the alleged "other woman" reportedly pregnant with Nick's second child ... while Nick and Iggy were still together.

Iggy's lawyer legal eagle, Howard King, didn't mince words in a letter they fired off to Keonna's lawyers, warning them, "Ms. Green has done enough to embarrass herself by her pathetic efforts to profit from Iggy's hard-won celebrity, all in exchange for whatever paltry sums she can garner in exchange for peddling tales of her tasteless exploits."

The letter goes on ... "Any mention of Iggy in your client's efforts to sell a story to whatever tabloid needs to fill its pages with the fetid story of your client's classless antics will be considered a violation of Iggy's rights of publicity ... subjecting Ms. Green and any publication that airs your client's soiled laundry to significant liability."

If she is pregnant, we're guessing no baby present from Iggy.

Russell Wilson is in real danger of being murdered by Future ... so claims Russell's fiancee, Ciara.

Ciara just filed legal docs in her defamation lawsuit against baby daddy Future, in which she lays out various threats Future has made. In particular, she notes the football emojis with guns pointing in their direction ... which Future posted a while back.

She also makes mention of the song he dropped last month, in which he says, "Tryna f*** my baby mama, dog what's up with you? You gon' make me get that heat, I'm pulling up on you."

The singer calls Future's conduct, "frightening" and "socially irresponsible ... where there has been a recent rash of gun violence."

Ciara believes the threat is real, but she doesn't explain what this has to do with her defamation case.

Yossi Dina just dropped a bombshell about the future of "Beverly Hills Pawn" ... there is none.

We caught up with the reality star in Malibu Monday when our camera guy asked if the show on Reelz is coming back for a 5th season. Check out the vid ... turns out Yossi wasn't totally in love with the show.

Louis Tomlinson is willing to settle his custody beef with baby mama Briana Jungwirth, but only if she agrees to keep their relationship and kid off social media.

TMZ broke the story, the One Direction singer filed legal docs for joint custody, because he claims Briana's denied him access to 5-month-old Freddie.

We're told Louis would like to avoid a court battle if they can come to terms. Louis wants pre-approval rights of any Freddie pics Briana wants to post.

For her part, Briana says she has a right as a proud mom to post pics of their son, and she says she hasn't trashed Louis so he has nothing to complain about.

As for the source of the conflict, Louis is convinced Briana is blinded by jealously over his relationship with Danielle Campbell, and she went crazy when Freddie came home with the smell of Danielle's perfume. Louis thinks things will be fine if Briana just moves on.

But we're told Briana fires back ... jealously isn't in her playbook. Her concern about Danielle is purely about Freddie ... she believes Louis' GF may be a crazed fan, and it worries her.

Johnny Depp has gone from calling Amber Heard the love of his life to the scum of the earth ... all with a simple tattoo alteration.

Depp inked his arm in Amber last year, shortly after they married. He inked the knuckles on his right hand, "SLIM" ... her nickname.

In the last week or so, he changed the L to a C and the I to a U ... and you don't need to watch "Wheel of Fortune" to know it now spells SCUM.

It's not the first time Johnny's tattoos turned ugly. Back in the day, when he was dating Winona Ryder, he had a tat that read, "WinonaForever." When that relationship fizzled, he changed it to "WinoForever."

#DontGetTattoos.

Gilbert Arenas says Iggy Azalea has no one to blame but HERSELF for the Nick Young cheating scandal -- saying she KNEW he was a dog who was going to mess around on her.

Louis Tomlinson is going to court for joint custody because he claims his baby mama is keeping him from their child because she hates his girlfriend, but she says the GF poses a security risk to the kid.

TMZ broke the story, the One Direction singer is now asking a judge to award him joint custody and equal access to 5-month-old Freddie, because recently she's been denying him access to the infant.

We're told Louis chalks the whole thing up to jealously. There have been lots of pics posted of him and Danielle Campbell, and he says the photos send her into a rage.

Louis says he and baby mama Briana Jungwirth have actually gotten along until recently and he was seeing the baby all the time, but things have now taken a turn for the worse.

As for Briana, we're told she says it's annoying that when Louis has the baby, he'll come back home smelling like perfume. But Briana's real problem ... she believes Danielle may be nothing more than a crazed fan who now knows her home address and gate security code.

Fetty Wap's baby mama is railing on the rapper, claiming he's put their daughter squarely in the crosshairs of Internet trolls who are now on the attack.

Masika says she and Fetty had a very specific deal to keep 3-month-old Khari out of the limelight, and he betrayed her by posting pics of the kid. Predictably, people on social media have gotten snarky, saying the kid doesn't look anything like Fetty so she must have slept with someone else.

Masika thinks Fetty's been a bad dad who was there for the birth and a doctor's appointment but that was it, and now he's trying to fool the world by making it look like he's a proud papa.

Fetty's telling Masika to pound sand, and he'll do what he wants.
