"Strong" trainer Adam Von Rothfelder has become instantly famous as the breakout star of the new show ... so like half of Hollywood it's not a big shocker nude photos have surfaced. 

Turns out Adam posed nude for an art project and the pics are ... impressive. The honchos on "Strong" were a little upset ... not because of the pics but because Adam didn't fess up before he was hired.

We're told Adam explained he didn't think it was a big deal because it's not pornographic. Producers saw it his way, so he won't be punished. It helps he's also a big reason people are watching. 

Dave Broome -- the creator of 'Biggest Loser' and "Strong" -- is a big, big fan of Adam's work ... telling us, "I am actually rather envious."

Christian Slater doesn't need a medical degree to know his father is suffering from manic depressive schizophrenia -- he says he's gotten all the evidence he needs from his mother.

The "Mr. Robot" star just filed docs to get his dad Thomas Knight Slater's defamation lawsuit tossed, and in the docs he says his mother first told him about his father's diagnosis. He says she told him Thomas was taken to Bellevue Hospital in a straitjacket in 1972 after threatening to kill her and Christian.

He adds his father also pushed his mom into a busy street when she was pregnant with Christian ... according to her.

And there's this -- Christian included copies of rambling postcards he says his dad sent ... telling Christian he'd be nothing without him. For instance, one read ... "I take FULL CREDIT: I'm the vital ingredient." 

We broke the story, Thomas sued his son for talking about his diagnosis in an interview.

Christian says his dad, an actor, hasn't worked since 1988 due to his mental health issues.

Mariah Carey is shacking up at Lake Como in Italy ... which means she can literally row over and ask George Clooney for a cup of sugar ... if she baked. Or rowed.

Mimi got hooked up with an 8 bed, 8 bath lakefront mansion by Airbnb ... where she'll stay during the Italian leg of her 'Sweet Sweet Fantasy' tour.  

The mansion -- named Villa Napoleon -- was built in the 18th century, and for $12k per night ... is packed with luxuries like 11 fountains, a greenhouse, private dock, children's playground, gardens, home theater, and a bell tower. Yes ... a 12th-century bell tower.

Michael Rainey Jr. might want to start renegotiating a contract for the next 'Barbershop' movie after the HUGE success the third installment just had at the box office.

According to his contract, the teen actor, who plays Jalen in the movie, banked $65k for "Barbershop: The Next Cut" ... which took in more than $20 million.

It's a decent payday for Rainey -- who also has a key role in 50 Cent's TV show, "Power." The bad news is ... he's getting zero back from the movie's success. Then again, he's only 15.

Pray for a role in 'Barbershop 4.'

Before this sippin’ sista was an Emmy nominated girl, she was just another ukulele playin’ lady in New York City. Can you guess who she is?

5:21 PM PT -- Adrianne just got a shout out from President Obama ... who wrote: 

"Thank you, Adrianne, for being Boston Strong. Terror and bombs can't beat us. We carry on. We finish the race!" 

SHE DID IT!!! 

Adrianne Haslet has just crossed the finish line in the Boston Marathon ... 3 years after losing her leg while a spectator at the very same race.

Ace Frehley can no longer rock and roll all night -- doctors orders.

TMZ has learned Frehley is back home resting after being rushed to the hospital Friday night for exhaustion and dehydration. The ex KISS guitarist was released Sunday night with one warning: slow down. 

Docs told the 64-year-old he's in great shape for his age, but needs to stop running around like he's still 18. He was advised to arrange a less exhausting tour schedule.

We're told Frehley already clocked in a dozen shows this month -- and was shooting a music video in L.A. at the same time ... flying back and forth to play his East Coast dates. Fortunately, the Saturday gig he had to cancel was his last tour date.

He plans to follow doctor's orders and stay off the road for a while.

Doris Roberts, the beloved mom from "Everybody Loves Raymond," has died ... TMZ has learned.

We're told Doris passed away Sunday in L.A.

She won 5 Emmy awards, 4 of them for 'Raymond.' She's also starred in tons of other TV shows and movies, like "National Lampoon's Christmas Vacation" and "Grandma's Boy."

She's survived by her son, Michael Cannata Jr., who she had with her first husband. Doris' second husband, William Goyen, died in 1983.

Doris was 90 years old.

We last saw her about a month ago where we frequently got her -- going to the movies at the ArcLight in Hollywood. Doris said she wasn't feeling great, but she was as witty as ever.

Joe Manganiello was sidelined over the last few days because of appendicitis and a surgery that was extremely serious ... TMZ has learned.

Sources connected with the actor tell us, Joe went into the hospital late last week to have his appendix removed, but when doctors went in they were alarmed. We do not conclusively know the nature of the problem, but one source says his appendix burst.

Joe, who cancelled an event Sunday, was still in the hospital as of last night.

Joe's rep has said he has a chronic condition and suggested that's why he missed his Sunday appearance. We know he ripped a bicep during shooting of 'Magic Mike' and had surgery as a result. We also know the bicep is an ongoing problem, but we're told appendicitis is what kept him away last week.

Rob Kardashian is now FULLY out of his shell ... he just talked to us about everything under the sun -- his wedding, his weight loss, and his biggest vice with Blac Chyna.

BlacRob just touched down at LAX -- returning from weekend appearances in NYC and Boston -- and he was a regular chatty Cathy. He addressed the story TMZ broke about producers making big money offers for them to televise their wedding. 

Sounds like they're not impressed with any of the deals. Yet.

Rob also says he's dropped 40-50 lbs. so far, but he's not even counting anymore because he's too busy being happy. Just watch -- honestly, it's been years, if ever, since we've seen Rob this talkative.

He even broke some news to us about his driver license -- and let's just say Uber's gonna love him!

Jared Fogle got what he deserved ... more than the maximum recommended sentence for child molestation ... this according to prosecutors who just submitted Fogle's text messages showing shocking depravity.

Fogle is asking an appeals court to throw out his 15.6 year sentence, claiming the judge should not have sentenced him to more than the max recommended in the plea deal -- 12 1/2 years.

The U.S. Attorney just filed legal docs saying Fogle's conduct warrants the harsher sentence, pointing to text messages he sent to a woman who apparently procured minors for his sexual pleasure.

In one text, Fogle writes, "Is your Asian friend available?" She responds, "Are you going to pay me, too, or can I come back?" He replies, "I'll pay you big for a 14 or 15-year-old."

Fogle and the woman then haggle over price -- he's willing to pay $400 if the child is 16 or younger. He then says, "Do you have any access to any young girls? Like 15 or 16?" She asks, "Why, baby?" He says, "Cause it's what I crave."  

Blake Shelton sent a message to his fans -- and possibly In Touch magazine -- about his boozing habits during his latest concert.

Blake played the Tortuga Music Festival in Fort Lauderdale this weekend ... and while onstage he took several healthy swigs from a cup that read, "I drink, get over it" -- and he made sure cameras captured the phrase.

Blake recently filed a defamation lawsuit against In Touch for its cover story about him hitting "rock bottom" and going to rehab. In Touch says there's no defamation, since Blake's proudly created a hard drinking image.

We suspect these pics might end up in court.

As Blake puts it (in song) ... "Cause the more I drink, the more I drink."
