Breakups

John Mayer has returned to form! It's just like 5 years ago, when he was the funniest celeb in the TMZ universe.

We got John at Madeo Monday night, and he was hilarious. A photog brings up the buzz that his ex GF Katy Perry was writing a song about him, and John was cool with the prospect. Hell, he's already been through it with Taylor Swift.

We also asked John about what our photog called "scientific proof" that songs with his name in it shoot to #1.

The clip reminds us of some of the best TMZ videos ever.

Katharine McPhee insists she's no cheating skank -- claiming she was SEPARATED from her husband last year when she publicly made out with another man.

TMZ has obtained McPhee's divorce docs -- she lists her date of separation from husband Nicholas Cokas as March 15, 2013 ... more than 7 months before she openly locked lips with married "Smash" director Michael Morris.

As we reported, McPhee filed for divorce from Cokas last week. She cites irreconcilable differences in the docs.

Also interesting ... according to the docs, McPhee wants to keep all the money she made post-separation ... which might explain why she picked such an early separation date.

McPhee and Cokas briefly attempted a reconciliation in March ... but that just didn't work out.

Somebody should tell "Two and a Half Men" star Melanie Lynskey Hollywood divorces are typically mean, ugly and humiliating ... search Sherri Shepherd, Master P, Kevin Hart, et al.

Lynskey and "Always Sunny in Philadelphia" star Jimmi Simpson just finalized their divorce ... and it's the nicest set of divorce docs we've ever read.

Neither one hired a lawyer. They worked everything out themselves -- with a little bit of help from a mediator.

Neither wants spousal support. As for splitting assets ... they've actually included a line promising not to take "unfair advantage" of each other.

The couple filed for divorce in 2012 -- citing irreconcilable differences.

If Mel Gibson ever has to fill out an employment application ... he can honestly say he has not been convicted of a violent crime ... because his battery conviction in the Oksana Grigorieva case has been expunged.

A judge has officially removed the conviction from Mel's record ... after he successfully completed his 3 years probation.

TMZ broke the story ... the paperwork had been filed to erase the conviction for hitting Oksana in the mouth and knocking out 2 veneers.

Mel has done his 16 hours of community service and 52 weeks of counseling.

Shelly Sterling says she will file for divorce from Los Angeles Clippers owner Donald Sterling "eventually" ... telling Barbara Walters she has signed papers before ... just never filed them.

In an interview scheduled to air later on Sunday, Sterling says she has not followed through with the divorce yet on the advice of her financial advisors.

Poor Canada -- The-Dream's ex-girlfriend would rather see him rot in jail than return to Canuckistan ... and that's exactly why the producer believes she has falsely accused him of strangling her.

Dream is telling friends, the reason he was charged Wednesday with felony assault and strangulation is all because Lydia Nam was about to be kicked out of the U.S.

Here's the deal. Her visa is set to expire shortly. Dream says she found out there's a special visa that allows immigrants to remain in the country if they're crime victims and they're needed in the prosecution of the perpetrator.

So, Dream says, that's why she FALSELY accused him of punching, kicking and strangling her while she was pregnant with their son.

For Nam's part, sources close to her tell us, Dream didn't just attack her once ... he had a history of physically abusing her. She admits she waited 7 months after the strangling incident to file a police report, but she says the reason for the delay is simple -- she was terrified of him.

Hilary Duff might have just made a $6,000 per month mistake -- she recently signed a lease for a fancy bachelorette pad ... but now she might be getting back together with her estranged husband Mike Comrie.

Real estate sources tell TMZ, Duff signed the lease for the 1,500 sq. ft. 2-bedroom house a couple months ago -- soon after she and the ex-NHL star announced they were separating -- but you may have noticed ... the "separated" couple hasn't been so "separated" recently.

Hilary and Mike have been hanging out a LOT -- Hilary even addressed the ambiguous situation, saying, "We love each other so much, and we love spending time together ... We don't know what our future looks like right now."

So it's unclear if Hilary plans to live in her new house ... or if she plans to let it sit Hilary-less, while she continues to live with Mike in their $3.9 million Beverly Hills mansion.

6:00 PM PDT -- Dream just posted $20,000 bail and was released from custody. He was ordered to stay away from Lydia.

10:35 A.M. PDT -- A rep for Dream just told TMZ, "Dream voluntarily surrendered to the Midtown North Precinct this morning in order to responsibly address the false allegations filed against him by Lydia Nam. He is innocent of the charges filed against him today."

The-Dream turned himself into cops this morning for an alleged attack on his ex-GF ... and TMZ has learned he's been booked for 2 felonies -- assault and strangulation.

Law enforcement sources tells us Dream walked into an NYPD precinct at 8:30 A.M. ET -- he had been wanted by police for questioning in connection with an alleged assault on his baby mama, Lydia Nam in April 2013.

TMZ broke the story ... Nam claims he punched, kicked, and strangled her while she was pregnant with his son. For some reason she didn't report the incident to police until 7 months later.

According to law enforcement sources ... Dream's been booked for the 2 felonies as well as 3 misdemeanors -- assault, reckless endangerment, and child endangerment.

Devastating blow to the Hollywood fitness craze known as Barry's Bootcamp -- the married couple behind the company has crumbled in epic fashion ... amid allegations of terrifying violence, drug and alcohol abuse, and more.

43-year-old Rachel Mumford has filed for divorce from 58-year-old John Mumford -- the man who provided the seed money in 1998 -- citing irreconcilable differences ... and that's just the beginning.

Rachel just got a restraining order, after accusing John in legal docs of physically abusing her for years. She also claims he's been nursing a nasty ecstasy and booze habit that's put not only both of them in danger, but the couple's children as well.

The straw that broke the camel's back -- Rachel claims she and John went to Paris last month, and John flipped out over text messages he read on her phone ... grabbed her, threw her against their hotel room walls, and attempted to smother her on the bed.

Rachel and John were married back in 1997 and have two minor children. Rachel wants physical custody of their kids while John gets help for his drug and booze problems.

Barry's has blown up with locations across the country -- and remains a staple in the Hollwood fitness scene ... with celeb regulars like Jessica Alba, Kim Kardashian, Hugh Jackman, Jake Gyllenhaal, and many more.

Selena Gomez has turned her back on former BFFs Kendall and Kylie Jenner because she wants to focus on what's really important -- MUSIC -- and thinks the Jenners are nothing but a toxic distraction ... sources tell TMZ.

Sources close to Selena tell us, the singer had an epiphany after Coachella last week -- where she was surrounded by booze and drugs while hanging with the Jenner girls, Justin Bieber ... and all the hangers-on that come with them.

We're told Selena's sick of that scene -- so she's decided to cut out what she considers the biggest sources of negativity ... Jenner girls included.

Selena made the cut official, and public ... by unfollowing Kendall and Kylie on Instagram. She also deleted all her Coachella selfies with the sisters.

The Insta-purge continued ... with Bieber and a bunch of others getting dropped -- and, in fact, she's currently following ZERO people.

We're told Selena is determined to stay on the straight and narrow -- focusing on music and, get this ... going to church almost daily.

Makes ya think ... must've been one helluva party at Coachella.

"Scandal" star Columbus Short is being allowed to return to his home -- after being banned from the premises for allegedly threatening to kill his wife -- but he won't have time to get comfortable ... a judge is giving Short just 2 hours at home to get his stuff ... and get out.

Short was in court today seeking permission to move back into his house after his wife obtained a restraining order, barring him from entering the home -- but a judge denied his request.

Instead, the judge gave Short 2 hours next Monday to go to the house and gather any belongings he needs ... and only with his attorney present.

TMZ broke the story ... Tanee Short got the restraining order, claiming Short had threatened to kill her during an explosive fight in their Chatsworth home April 7. Tanee claimed Short pinned her down, choked her, and threatened to stab her unless she admitted to having affairs.

She also claimed Short put a knife to her throat and threatened murder/suicide.

Marriage was NOT as good as it gets for Cuba Gooding Jr.'s wife -- she just filed for separation from the Oscar-winning actor after 20 years of marriage, TMZ has learned.

Sara Kapfer filed today in L.A. County Superior Court, citing irreconcilable differences. She and Cuba were high school sweethearts and got married in 1994. They have 3 children, 2 of whom are minors.

Sara wants joint legal and physical custody. According to the docs, child support will be determined later.

It's surprising -- just last year, Cuba gushed about his wife on "The View," talking about how wonderful it is to be married to someone for so long.

This is not a trick, Michael -- "Arrested Development" star Will Arnett has officially filed for divorce from Amy Poehler ... nearly two years after the couple separated.

According to court documents, Arnett wants joint legal and physical custody of their two sons aged 5 and 3. He also wants visitation.

43-year-old Arnett and 42--year-old Poehler got married in 2003.

Since they separated, Arnett has reportedly been dating Billy Joel's ex-wife Katie Lee and Poehler has been linked to comedian Nick Kroll.

Journalist and TV host Giselle Fernandez just lost 180 pounds ... by dumping her husband after 11 years of marriage ... and according to legal docs, she's quick to point out ... she makes a fortune.

52-year-old Fernandez filed for legal separation from business exec John Farrand on Friday, citing irreconcilable differences.

And this is interesting ... Giselle is NOT asking for spousal support, saying in her docs, "I was the breadwinner." Giselle claims she typically works 40 hours a week and earns an impressive $41,667 per month.

Other fun stuff -- Fernandez claims she spends $6,500 a month on rent and $2,000 on GROCERIES.

The couple was married at their Beverly Hills home back in November 2002. They have a 7-year-old daughter, and Giselle wants joint custody.

In addition to "Access Hollywood," Fernandez guest anchored for "CBS Early Show," "CBS Evening News," "NBC Today," "NBC Nightly News," and even appeared on "Dancing with the Stars" (she didn't last long).

Johnny Weir wrote a 5-page post-nup which is part of his newfangled reconciliation package with Victor Voronov -- and Johnny makes it clear mutual masturbation will NOT be tolerated.

TMZ broke the story ... Johnny and Victor agreed over the weekend to call off their divorce, but Victor wanted Johnny to sign a document apologizing for trashing Victor in the media and promising to keep Johnny's mom out of their relationship.

So Johnny fired back with a document of his own, which, among other things, defines the type of cheating that will not be tolerated. The document -- obtained by TMZ -- lists the following:

-- sex outside the marriage
-- oral sex outside the marriage
-- kissing or making out
-- sexting
-- aggressive flirting
-- mutual masturbation
-- social media/grindr/dating

And it gets better. According to the document, if either one has a situation where they're "in close range or contact with someone from our past or someone to be part of the future" ... the other can veto the contact. Johnny specifically gives an example of a figure skater he dated.

The document also requires joint STD tests every 6 months with the results being read with both in the room.

And there's a section about splitting assets if they ultimately get divorced: "Should a gift be given, i.e., the Cartier Roadster (R.I.P.), the gift belongs to you." Someone broke the watch!

And finally ... there's a section titled "Ultimatums." Johnny lists examples of Victor's ultimatums, including, "If I give you one more day to get your bank records to me, then I want to have a free f*** of anyone I want."

Simply fabulous.

Hilary Duff and Mike Comrie don't look like people that recently separated ... instead, they were hanging together at Coachella this weekend looking every bit the married couple.

Duff and her NHL player hubby announced their separation back in January, but still managed to take a family vacation together over Valentine's Day (see below).

Perhaps this relationship isn't over until the divorce attorney sings.
