Yesterday Katie Holmes brought little miss Suri to work, and the celebritot got to watch her mama shoot scenes with onscreen hubby Channing Tatum.

During breaks we spotted Katie spending time with her darling daughter, and Suri didn't exhibit any divalike behavior at all. Hmmm, maybe she's fascinated with showbusiness? We could totally see her getting into it!

Mmkay, she almost has this whole exercise thing figured out!

Former O.C. beauty Mischa Barton seems to have let that Brandon Davis Tweet (real or fake) get to her, because we spotted her in some super-tight gym clothes after working out today. Props to her! Only problem is, Mischa later went to Urth Caffe in West Hollywood to chow down on some grub...

The actress pulled a similar stunt last week - she's really gotta stop loading up on carbs after the gym! Don't cancel out your efforts, girl.

A source tells X17online exclusively Sandra Bullock has moved to a rented home in an exclusive neighborhood of Los Angeles -- just far enough away from the media spotlight -- and is enjoying time there with her estranged husband Jesse James' three kids.

We are told James' mother Carol, drove the kids over to Bullock's new pad. Sandra is believed not to have been staying at her Hollywood Hills home since just after she was visited by pal George Lopez last Monday, April 5.

Our source says spending time with Sunny, 6; Chandler, 15; and Jesse Jr., 12 has given Sandra the strength she needs to get through this tough time:

"She is really happy right now. The kids have really made her feel good. She's thrilled that she has impacted their lives. Sandra is much better and stronger than she was a couple of weeks ago. When this thing dies down Sandra will emerge stronger than ever."

We're told Bullock is definitely planning to divorce James after a cheating scandal to rival that of Tiger Woods rocked the couple's marriage:

"When Jesse's out of rehab [in Arizona for sex addiction], the divorce will speed up."

She also loves working out, stocking up on Starbucks and taking out the trash! Because that's exactly what we caught her doing yesterday. Sunday fun-day?

Speaking of Bradley Cooper's girlfriend... where is Bradley Cooper? I know Renee knows how to keep busy 24/7 and Brad is shooting movies all the time now (due to The Hangover) but does the couple EVER have "alone time" anymore?

This is totally the next Kardashian (well, Kardashian-Jenner) to watch out for!

Supermom Kris Jenner took her darling daughter Kendall to the Lakers game at Staples on Sunday to watch Lamar Odom play - they're both such fashionistas! Think Kendall will be showing up to perfume launches and video game parties like stepsister Kim anytime soon?

Eric Dane and Rebecca Gayheart recently welcomed baby girl Billie Beatrice into the world, but we haven't exactly seen her yet! We spotted the twosome arriving home the other afternoon - Eric was a total gentleman and even held the door open for his lovely wife - but still no glimpse of their daughter. Hopefully soon! You know she's adorbs.

From the streets of New York City to the sands of Abu Dhabi! The extended trailer for the SatC sequel makes it look like the actual movie will be absolutely ridiculous, and this poster only confirms it. Where will Carrie and co. go next? Maybe the North Pole?

Whoa, who knew Ryan Phillippe would one day talk about this? And to Howard Stern, no less!

The Crash actor dished about his ex on the shock jock's Sirius XM radio show today, and admits he's tired of the way he gets treated by the media. Ryan reveals the following:

"I've been dumped on in the press for relationship stuff since Reese [Witherspoon] and I divorced. I'm tired of getting sh*t on. I don't feel like I deserve it. Things happen! How many people have you broken up with over your life?"

Phillippe even claims that he and Witherspoon are such "great friends," they call each other up after breakups! Mm-hmm, sure, okay.

He also says that he and Reese have not had ex-sex. "That hasn't happened," Ryan tells Howard. Not yet at least!

Maybe he and Reese will reunite one day? She might have a new beau now - Jim Toth - but Ryan has split with Abbie Cornish, so who knows!
