Jennifer Love Hewitt was all smiles when we caught her leaving a lunch meeting in Beverly Hills on Friday, and earlier in the day the 33-year-old actress tweeted, "I hope everyone has a great day! I have lots of meetings and work today but first yoga!...;)"

J. Love IS looking pretty fit, and heck, she might even be back down to a size two! We're guessing all that cardio she did to prep for her lingerie-clad character in The Client List has paid off ... now if only she had someone to appreciate it!

Thankfully the starlet has stopped talking about Adam Levine, but we wanna know who she's going to go after next. After all, she did tweet at Joe Jonas last month ... she's definitely on the prowl!

Oops she did it again!

After allegedly storming off the set of The X Factor on Thursday, Britney Spears reportedly walked off in the middle of auditions on Friday as well.

"After a very popular contestant finished, Brit stood up and immediately walked towards the tunnel where judges enter," a show source tells Us Weekly. "Her bodyguards [and entourage] jumped up and ran after her. She was moving fast ... It was odd." After "a little while" the 30-year-old pop star came back as if nothing had happened, but no one seems to know why she's been so moody since auditions started in Austin the other day!

After a "stripper" reportedly "butchered" Brit's song "Hold It Against Me" on Thursday, she stomped off and was absent for performances by no less than four contestants. Brit denied the reports on Friday, tweeting, "#Britneywalksoff??? LOL was just taking a little break people. I am having the BEST time!!!" Umm, that's an awfully long potty break Brit!

Russell Brand was spotted leaving his studio on Friday, and the British comedian turned heads in a pair of skinny tie dye jeans and a ripped t-shirt. While he may not have the best style, he certainly seems to get enough action from the ladies, so obviously he's doing something right!

She may be wearing semi-frumpy clothes and no makeup, but Natalie Portman is still a knockout!

We spotted the Oscar winner braving the windy weather at the grocery store on Friday afternoon, and it seems as though we caught her during a break from filming Lawless. After giving birth to son Aleph nearly a year ago, Natalie has been keeping a pretty low profile, but she's getting back into the swing of things with the upcoming drama, which is about "sexual obsession and betrayal set against the music scene in Austin, Texas," according to IMDb. The flick also stars Ryan Gosling, Christian Bale, Cate Blanchett and Rooney Mara. Can't wait to hear more!

It may have been boyfriend Robert Pattinson's premiere, but all eyes were on Kristen Stewart as she worked the red carpet in a sexy crimson Reem Acra number, at the Cannes Film Festival, on Friday evening.

But the Twilight star walked the Cosmopolis red carpet with another man -- her On the Road co-star, Tom Sturridge.

As of now, Rob and Kristen are to appear onscreen for the last time when the final installment, The Twilight Saga: Breaking Dawn - Part 2, hits theaters this November. At least they still have each other!

Dem babies sure are cute!

The Vision of Love singer has more than enough to smile about. Work those cameras, girlfriend.

Katherine Heigl has just adopted daughter, Adaleide Marie Hope Kelley, so it's no wonder the mom of two has no time to primp in the a.m.

The One for the Money star kept it causal in a flannel and no makeup, as she surveyed a U-Haul moving truck outside of her home in Los Feliz, on Friday afternoon.

The proud new mom is enjoying being a parent with hubby Josh Kelly, and she recently gushed of the singer, "He's a great dad. I am a little bit shocked. I didn't expect it. He's such a guy!"
