Sandra Bullock had a wild Wednesday night!

The actress enjoyed dinner at Mr. Chow before heading over to the white hot Beacher's Madhouse at The Roosevelt in Hollywood, where she stayed until 2 a.m. Sandra knows how to party!

Bullock looked dazzling in dangly gold earrings. We're glad she had a night out to relax -- this week Sandra's rep had to deny rumors that she's "obsessed with being skinny," as one magazine cover claimed.

And she has better news to celebrate -- the trailer for her new flick Extremely Loud and Incredibly Close debuted Wednesday to rave reviews. The movie comes out in December and is already getting Oscar buzz! Watch after the jump.

Ashton Kutcher's alleged "fling" has been identified as 23-year-old blonde Sara Leal.

Various online reports claim Leal hooked up with the Two and A Half Men star on the 12th floor of San Diego's Hard Rock Hotel ... on the same weekend of Ashton and Demi's sixth anniversary. The couple spent the weekend apart.

Leal is reportedly demanding $250,000 to keep the story under wraps, according to TheDirty.com. A source tells the site the 33-year-old actor told her, "Kutcher told Sara Leal that him [sic] and Demi Moore are separated and the public doesn’t know yet."

Ashton's wife of six years, 48-year-old actress Demi Moore, recently Tweeted, "When we are offended at any man's fault, turn to yourself & study your own failings. Then you will forget your anger."

TheDirty adds Kutcher's bodyguard took Leal's cell phone number before she came into the hotel room.

Reps for Demi and Ashton have not commented on the matter.

Jennifer Love Hewitt showed off her sexy wheels as she cruised through LA in her white-hot Bentley convertible, on Wednesday.

The actress has been busy getting cozy with Eagle Eye actor Jarod Einsohn. The new pair was spotted enjoying a romantic dinner at Katsuya in Los Angeles immediately after Jen returned home from New York Fashion Week.

Rumors swirled that Hewitt was set to be the final celebrity guest judge for Project Runway, when she sat next to Heidi Klum and Michael Kors as the Season 9 finalists presented their collections at Fashion Week, but another fashionista has already landed the job.

One of the few lucky ladies who can go totally bare-faced and still look beautiful, Katie Holmes beamed as she happily chatted away on her cell after a shopping trip to Maxfield in LA, on Wednesday.

The Jack and Jill star stepped out looking like the girl next door in a low-key ensemble of dark jeans, flow-y black top and boots -- only her giant wedding ring, and a hovering bodyguard, gave away her Hollywood A-list status.

It was recently announced Mrs. Tom Cruise would play the important role of the "Slutty Pumpkin" on the upcoming Halloween episode of How I Met Your Mother.

The "Pumpkin" character has always been an important part of the series, but was never actually revealed -- until now!

The competition continues to heat up, and David Arquette came fully prepared for his long day of practice with a packed lunch big enough to fuel him though the daunting dance day, on Wednesday.

And rather than bringing his own food, DWTS fan favorite Chaz Bono showed up with his own pair of dancing shoes -- black suede "Michael" boots with a "Latin" heel.

Since Bono has been struggling with painful knee problems during his routines, these comfortable boots may be just what he needs to aid those swollen ankles and bump up his score for next week.

It's her first day of freedom from those grueling Dancing With the Stars rehearsals, so Elisabetta Canalis treated herself to a low-key shopping trip with her adorable pups in Beverly Hills, on Wednesday.

The Italian TV personality was eliminated from the show last night after scoring a total of 21 out of 30 points for her dance routine with partner Val Chmerkovskiy, but was her dance performance really to blame?

Struggling to dance with injured knees, Chaz Bono had a hard time getting through his dance routine and scored a mere of 17 points, the lowest of the night.

Is Dancing With the Stars based completely on skill, or is it more of a popularity contest?

Is Jennifer Aniston in a nesting stage already?

The Friends star kept up her recent spree of purchases, this time buying home goods from ABC Carpet and Home in New York City Wednesday evening.

The actress has been stocking up on goodies to make the pad she just purchased with BF Justin Theroux in the Big Apple feel more homey.

We can only imagine how fab the place is going to look when Jen is done shopping!

Hilary Duff celebrated her 24th birthday on Wednesday, and she got a special surprise from our photogs!

Our paparazzi gave Hil some b-day roses as she left the vet with her pup, Lola. She Tweeted a cute thank you:

"Just left the vet w/Lola(just a checkup) and got serenaded by about 20 paps with roses and a happy bday song! Very sweet and funny!"

Glad you liked it, Hil! Happy birthday!
