It's officially the biggest divorce settlement in Hollywood history, and now Mel Gibson will be forced to fork over exactly half of his estimated $850 million.

The Oscar-winning actor's divorce from Robyn, his ex-wife of nearly 30 years, was finalized Friday in a Los Angeles courtroom. Since there wasn't a prenup, Robyn was entitled to exactly half of the actor's amassed fortune.

And that's not all. Gibson's ex will also be entitled to half of every future check he receives for the rest of his life -- that's a lotta dough!

The ex-pair, who have seven children together, will also have the task of divvying up Mel's assets, including over $100 million in real estate investments, the $600 million he made from The Passion of the Christ, and $75 million from other various film and TV projects he's executive produced.

Robyn has already been given two of the pair's Malibu estates worth an estimated $22.5 million.

Gibson first met Robyn in the late 1970s while she was working as a dental nurse. At that time, his first breakout film, Mad Max, had just hit theaters.

Samantha Ronson couldn't stop smiling as she strolled through Beverly Hills with a friend (in a very nerdy holiday sweater), on Thursday afternoon.

The celebrity DJ has been getting into the Hanukkah spirit with her family this week, and we can't help but wonder if Lindsay Lohan's Playboy mag was one of the 8 gifts she received this year. Lilo may have even sent a signed copy over herself; they are next door neighbors after all!

Miss Ronson had a bit of bad luck recently when a burglar broke into the garage of her Venice home, stealing $1,000 worth of unknown stuff. A 911 call was made at 7pm, but by the time police showed up, the perp had fled the scene.

Could Lilo have placed the call?

Robert De Niro and wife Grace Hightower are parents to a newborn baby girl.

Helen Grace was born via surrogate weighing 7 lbs., 2 oz.

De Niro, 68 and Hightower met in 1987 and already have a 13-year-old son named Elliot.

The Oscar-winning actor has two other children with former wife Diahnne Abbott .... as well as twin sons with ex-girlfriend Toukie Smith.

Congrats!

Suri Cruise has expensive taste, so it's no wonder Katie Holmes has been seen doing most of her Christmas shopping at Barneys!

We spotted the actress shopping at the posh Rodeo Drive shop solo, and she looked a bit stressed out from all of the holiday madness.

It's no wonder, considering Suri reportedly requested $130,000 worth of gifts from Santa this year, including a pony, $15,000 diamond earrings and $1,500 custom made fairy princess gowns.

Daddy Tom Cruise also splashed out $5,000 last week to rent out the Rockefeller Center ice rink’s “Igloo,” a VIP-like area where the fam won't have to wait in line, and they get their own private space to warm up, according to the New York Daily News.

And get this -- TomKat paid to have the VIP area stocked full of hot chocolate from Serendipity 3 and sweets from Jacques Torres, brought in “especially for Suri.”

What more could a 5-year-old ask for?

When you're Kris Jenner, shopping at Louis Vuitton in Los Angeles is no biggie!

Kim Kardashian's mom hit the pricey boutique, wearing sunglasses and a houndstooth trench, to pick up a few Christmas gifts. Notice Kris' white Hermes bag. Guess a girl woman can't have too many mega-expensive purses.

Kris and the entire Kardashian family have been up to their eyeballs in drama ... not from their E! reality show, but from a Star report that claimed their clothing brand was created in Chinese sweatshops.

Star’s report quoted the Institute of Global Labour and Human Rights as saying the family is “taking advantage of these workers” and “holding hands with a government that spits on democracy and women’s rights.”

Though it's been reported that the family is preparing to sue the magazine and organization for libel, a source close to the Kardashians told X17online that there are currently no plans for a lawsuit.

Looks like Kris isn't too worried. When the going gets tough, the tough get going to Louis Vuitton!

Gabrielle Union is, without a doubt, a gorgeous gal!

The 39-year-old actress hit the waves with her NBA boyfriend Dwayne Wade's sons, Zaire and Zion. We absolutely love her orange bikini!

Although Wade didn't accompany his girlfriend to the beach, she didn't seem to mind keeping the boys company.

Union is set to have a busy 2012 with starring roles in two movies ... Think Like A Man and Tyler Perry's Good Deeds.

All she wants for Christmas is a sweet new $1.39 million pad!

Rose McGowan has just plunked down $1,390,000 on a 3,000 square foot, 4 bed/ 3.5 bath home in LA's Hollywood Hills neighborhood, and it's definitely a Charmed property.

The mid-century home rests atop a steep slope and boasts a two-car garage, a double-sided fireplace that divides the "formal" living and dining rooms, a custom designed built-in floating corner buffet, a backyard terrace, a gourmet kitchen with state-of-the-art appliances, and an all-glass entryway.

The backyard is perfect for entertaining, with its cozy covered area complete with heaters, and an outdoor fireplace.

The Conan the Barbarian actress decided to "downsize," after recently selling her Los Feliz home in May for $1,775,000.

JAG Jeans

Yes, Lindsay Lohan looks good with her clothes on, too!

The 25-year-old starlet, whose Playboy magazine issue is selling like hot cakes, is now the face and body for JAG Jeans. Seriously ... Lilo and campaigns go hand in hand.

In this sexy photo shot by photographer Yu Tsai, Linds is rockin' short jean shorts, a white fringed vest and serious bedhead.

Tsai said the following about Lilo:

"'As Jag Jeans' newest endorser, Lindsay embodies the strength and fearlessness of the woman of today. She is unafraid to be who she is. She is fierce yet exudes feminine grace. Lindsay was so involved with the shoot that she would go as far as adjusting items on the set.

Sounds like Lilo was a sheer pleasure to work with. Keep up that great work ethic, Linds!
