Last night Charlize Theron hosted the official launch party for Rage at Chinatown's Historical Central Plaza in Los Angeles, and she was joined by famous faces like Rumer Willis, Dane Cook, Stacy Keibler, Michelle Rodriguez and Sophie Monk.

Rage is not a hip Hollywood club, but rather "a first-person shooter video game that takes place in a post-apocalyptic world." The Black Keys performed at the star-studded event, and we even spotted a Glee actor in the mix!

Yesterday we photographed Kristin Cavallari, Chaz Bono, David Arquette and several others leaving rehearsals for Dancing with the Stars, and as usual, everyone was friendly with photogs after practicing with their pro partners.

Of course, KC wasn't the only hot blonde we spotted ... Lacey Schwimmer showed some skin when we snapped her returning to her car:

Er, mom jeans? Either way, we're not sure these were the best choice in bottoms for Jennifer Love Hewitt.

The actress was spotted running errands in Toluca Lake on Friday, and she appeared to be in a great mood, but it also appears as though her pants might be a size too big. Does that mean she's a size zero now?

Check out another shot after the jump and let us know what YOU think about J. Love's denim...

He usually gives X17 photogs his very best poker face when we spot him out on the street, but yesterday Ryan Phillippe flashed us a knee-weakening smile as he left Fred Segal in West Hollywood.

The 37-year-old actor/daddy rocked a YMCMB shirt (who knew he was a fan?), and we're not sure what's in the bag, but maybe it's a gift for baby mama Alexis Knapp or their daughter Kailani?

Yesterday Maria Shriver lunched with a female friend in Brentwood, and she appeared to be in a much better mood than she was earlier this week when met up with soon-to-be ex-husband Arnold Schwarzenegger and their son Patrick at the Miramar Hotel in Santa Monica.

Arnold has kept a relatively low profile after he admitted to fathering a teenage son with former housekeeper Mildred Baena back in May, but it has recently been revealed that he plans to pen a tell-all book about his life, which will go into details about the affair and his split from his wife of 25 years. The book is tentatively called Total Recall: My Unbelievably True Life Story, and his rep told the press, "He has been keeping notes and working on the book for over a year. He didn't want to write his autobiography while he was governor."

Hmm, wonder what Maria and the kids think about that?

Sofia Vergara was spotted checking out boots at Barneys on Friday afternoon, and it looks like the Colombian beauty was having a difficult time making a decision!

In addition to shopping and starring in a hit show on ABC, Sofia's also been busy with her KMart clothing line, Sofia. "I always wanted to do it," she recently told the Associated Press. "I always had the thing for fashion, for beauty. But, I always wanted to team up with somebody like Kmart because that is what I wanted to create, a line that was affordable, that was for women of all sizes, every ethnicity, that could make them feel cute and beautiful without spending thousands of dollars."

Well put! So does she actually wear clothes from her collection? Click after the jump to see what she said about that!

Look at that precious little face! And that well-groomed hair! And no, we're not talking about Aubrey O'Day...

The singer and a pal were spotted taking their pups to coffee in Studio City on Friday, and despite the Little Mermaid-esque 'do, Aubrey kept her outfit cute and casual. Hmm, no cleavage or high heels? Is it possible the former Danity Kane starlet is finally realizing that less is more?

Hey, at least she kept her girls covered up this time...

Club Fluxx

Ashton Kutcher has had quite the week -- he's had to dodge allegations that he cheated on his wife Demi Moore with a 23-year-old blonde.

Sara Leal claims she hooked up with the Two and a Half Men star at Fluxx in San Diego last weekend, and now pictures have surfaced proving the star was, indeed, at the club. Ironically, it happened to be the same weekend of his sixth wedding anniversary to Demi.

A source inside the club tells X17online exclusively:

"Ashton was having a blast in the VIP section drinking with his buddies. Then his group went to the dance floor and he was checking out the girls while they danced. Out loud he said, 'None of these girls are hot tub-worthy.' He didn't seem to care who was listening."

Ashton was seeing partying with his former That 70's Show co-star Danny Masterson and Danny's brother Christopher.

Earlier today, Ashton and Demi spent the morning together at the Kabbalah Centre in Los Angeles. Despite the affair allegations, both stars continue to wear their wedding rings.
