TGIF

Who really needs 11,000-square-feet of living space? Not Hollywood legend Warren Beatty ... because he just sold his ginormous Beverly Hills mansion for a cool $6.7 million.

Beatty and his wife, Annette Bening, had listed the 6-bedroom, 8-bath estate for almost $7 million back in June.

Just 3 months later -- with the help of celeb real estate agent Kurt Rappaport -- they scored a serious buyer, who we're told is a Swedish hotel magnate.

It was a ménage à trois dinner date, as Cameron Diaz got cozy with new bestie Gwyneth Paltrow and her Coldplay hubby Chris Martin while enjoying some sushi at Sugarfish in Brentwood on Monday.

Bruce Willis and Demi Moore's eldest daughter, Rumer Willis, showed off her A-list genetics by flashing her smokin' hot bod in a black bikini in Cancun this weekend.

Another member of Hollywood royalty has gone two pieces.

Another bogus celebrity lawsuit has been filed in federal court ... this time, the troublemaker claims to be Chris Brown ... and he's filed an INSANE lawsuit against Rihanna.

TMZ has obtained the documents, filed in U.S. District Court in Tennessee ... in which "Chris Brown" is requesting a restraining order against Rihanna because he fears she will cause him bodily harm.

The suit contains the following (completely untrue) allegations:

-- "[Rihanna] gave me herpes and then when I threatened to file a lawsuit against her for not telling me she was infested with genital blisters she began to hit herself in the face and throw herself into walls just as Jim Carrey did in the movie 'Liar, Liar."

"Then she turned around and blamed me for the matter as a form of punishment."

-- "I woke up with three blisters on my penis ... this isn't just a regular case of American herpes, this is a case of Herpes from Barbados, which is most likely lethal."

The accuser is demanding $10 million ... along with "a restraining order against Rihanna and her case of genital herpes immediately."

TMZ broke the story ... someone claiming to be Selena Gomez's father filed another bogus lawsuit in Michigan -- accusing Justin Bieber of stealing his credit card for a penis enlargement.

Justin Bieber bought himself a penis enlargement with a stolen credit card ... and he's also cheating on his GF with Ke$ha, Rihanna and Penelope Cruz ... this according to a CRAZY new lawsuit filed in court and obtained by TMZ.

Bieber has been sued in Michigan by a man claiming to be Selena Gomez's father -- who makes some of the most insane, and obviously untrue allegations ever documented in court.

Among the highlights:

-- "Bieber has cost me $426.78 and never paid me back. This money was used as abortion money because Justin Bieber got my daughter Selena pregnant in my bedroom, on my canadian bear rug."

-- "Usher Raymond came to my house on the forth of july 2012 and sodomized me with a firework and lit it inside my anal area while blaring kate perry [sic] firework song in my ear drums."

-- "[Bieber] gave selena a std and Bieber stole my credit card to buy him and sean p-ditty [sic] combs cocaine to use in drug free school zones."

-- "Bieber also got a penis enlargement with my stolen american express card. "

The lawsuit concludes ... "I'm an emotional mess ... America must boycott biebers music!"

President Barack Obama has offended the bayonet community ... TMZ has learned.

TMZ spoke with multiple people in the bayonet industry who tell us they were shocked and even offended when Obama brought up the weapon during last night's debate.

FYI -- Obama was going after Romney when he said, "You mentioned the Navy, for example, and that we have fewer ships than we did in 1916. Well, Governor, we also have fewer horses and bayonets, because the nature of our military's changed."

According to the official U.S. Marine Corps website, every Marine is STILL required to complete a bayonet training program ... because "the weapon becomes just as effective [as a rifle] in close combat situations."

We spoke with Dan Riker from Bayonet Inc. -- a leading military surplus outlet that specializes in bayonets -- who tells us he believes Obama's comment was "ignorant ... because our soldiers still use bayonets."

He adds, “[Bayonets] are still distributed to the military all the time -- he should get educated on it”

Lindsay Lohan reentered the NYC party scene last night -- where she was arrested last month -- raging until 3AM ... and TMZ has the footage.

Lohan must've been pining for some raw fish -- 'cause she rolled into Catch in the West Village -- a fancy, bumpin' sushi joint that's been described as "lively and loud."

Lohan didn't leave the place until 3:15 AM -- beelining straight for a waiting SUV that whisked her away. The move might've been a message to Michael Lohan -- who's leading efforts to get Lindsay into rehab.

But it wasn't all tuna rolls and club music for Lohan last night -- she actually watched the debate ... and even tweeted support for Barack Obama during the event ... writing:

"RT @BarackObama: RT if you're #ProudOfObama as our commander in chief."

Funny, considering she JUST announced her support for Mitt Romney two weeks ago.

Donald Trump has made it clear … the information he has concerning the President of the United States is HUUUUGE … and he tells TMZ he’s going to reveal the info on Wednesday.

Trump just called in to “TMZ Live” and told us the information is nothing short of “a big fact.”

When asked if his secret will make Obama happy – Trump replied, “I don’t wanna comment … that’s up to him.”

Eva Longoria has a nasty red blotch on the back of her neck -- and she's probably THRILLED about it ... 'cause it used to be a tattoo of her ex-husband's basketball jersey number.

Back in January, Longoria began laser treatments to erase 3 Tony Parker-inspired tats -- the "NINE" tattoo ... the wedding date tattoo on her wrist ... and Tony's initials (which were put on a very private, undisclosed location).

Tattoo removal doesn't happen overnight -- it takes multiple sessions, which have to be spaced out over several months.

Brian Austin Green just learned a $200,000 lesson ... you snooze, you lose ... 'cause a judge just threw out his lawsuit against baby mama Vanessa Marcil because he waited WAYYYY too long to file.

We broke the story ... B.A.G. sued his baby mama/former "90210" co-star Marcil ... claiming he began lending her money in 2000 ... and when he came to collect the roughly $200k debt in 2011, she told him to pound sand.

But today, an L.A. County Superior Court judge ruled ... Green had waited too damn long to pursue legal action against the mother of his 10-year-old son ... and the statute of limitations had run out.

And it gets worse for Brian ... 'cause the judge also told Marcil she can seek monetary sanctions from Green for what her lawyers called a "frivolous" lawsuit.

For the first time since he separated from his wife, Danny DeVito appeared in public this weekend ... and told TMZ he's doing OK in the wake of the split.

A freshly bearded DeVito was lunching with some friends in Malibu -- sans his estranged wife Rhea Perlman -- and when we asked how things have been going since the announcement, he gave us a big thumbs up and told us, "Everything's good."

Michael Lohan will go to court in an attempt to get a conservatorship for his daughter, Lindsay Lohan ... TMZ has learned.

Michael has told an attorney, his daughter is in the danger zone ... a substance abuser, he says, who is hanging with the wrong group of people, including Dina Lohan.

Michael will meet with lawyers early this week, and there's one thing he does want -- he will NOT become Lindsay's conservator, because he doesn't want to run her finances so people will pass it off as a money grab. We're told Michael wants the judge to decide who to appoint conservator, but he says it CAN'T be Dina.

Michael told the lawyer the first thing he will do if there's a conservatorship is convince the conservator to send Lindsay to rehab, without the influence of the other people in her life. Michael says every time Lindsay has been to rehab -- including at Cirque Lodge and Betty Ford -- "She went in dirty and didn't come out clean," and he blames it on the people in her life who helped fuel her addiction.

Michael also told the lawyer he wants the conservator to somehow convince Dina that they need family therapy. He says Dina has always refused it in the past, and it has been a big stumbling block in Lindsay's recovery.

We broke the story ... Lindsay's entire management team, including her lawyers, were all involved in Michael's attempted intervention Friday. Turns out ... it wasn't just his idea. People are alarmed.

Former NFL star Bob Whitfield has 21 days to fork over $75,000 to his reality star ex-wife Sheree Whitfield for overdue child support ... or else.

According to legal docs obtained by TMZ ... Bob admits he failed to make 38 monthly child support payments of $2,142 to the "Real Housewives of Atlanta" star ... more than $81k.

Bob claimed he simply didn't have the money -- and had asked the court to lower his obligation ... but that was denied.

Now, the two sides have struck a deal in which Bob has agreed to hand over $75k before Nov. 11 ... or face the consequences in court.

In addition to the $75k, Bob has also agreed to pay $1,000 per month for the next 12 months -- before reverting back to the original $2,142.
