Britney Spears's face is front and center on the cover of Out Magazine, but inside the issue it's all about her hot body. She wore a revealing leotard that showed off two inner thigh tattoos and her bare behind in the spread, which was photographed by Ruven Afanador. The photo shoot is just the latest in a string of sexy poses for Britney, as she gears up for the release of her new album, Femme Fatale, this month. She was also game for a fun Q & A session where she touched on sex, family, and fame. Here's more:

• On regretting making any of her songs: "No. All of my songs are f*cking amazing."
• On the best advice she's received: "My mom said when you have a bad day, eat ice cream. That’s the best advice. "
• On the perks of fame: "Being able to reach people and hopefully make them happy."
• On plastic surgery: "When it’s time to pull and tuck, I’m sure I will consider it."

Sarah Jessica Parker and Christina Hendricks changed into matching Uggs between takes on the set of I Don't Know How She Does It in Boston earlier today. SJP has had lots of famous costars on set while shooting the film in addition to Vivienne Westwood spokesmodel Christina, like Jessica Szohr and Kelsey Grammer. SJP's doing double duty between her home life and work, spending time with her three kids and bouncing between two big-screen projects — she's one of the many actors with a role in Gary Marshall's New Year's Eve along with Halle Berry, Zac Efron, and Katherine Heigl. The follow-up to Valentine's Day may not be the only franchise SJP's involved with, as there is talk of a third installment of Sex and the City.

Channing Tatum joined his costars at the London premiere of The Eagle this evening, stopping to sign autographs for fans as he made his way into the theater. The battle epic opened in the States last month, but Channing and the film's other main man, Jamie Bell, just kicked off their UK press tour this week. Channing played an officer in the Roman army in the physically demanding period piece, and took advantage of the brief break between promotional duties to get surgery on his leg and recover close to home. The actor is overseas for now, but fans here can get a good look at him in the shirtless spread he posed for in the latest issue of GQ.

Katie Holmes left her apartment in windy NYC today in a camel coat. The actress was solo this afternoon, but brought Suri Cruise as her date last night to see a Broadway show. The mother-daughter duo returned to the Big Apple after spending some time with Tom Cruise in Vancouver, where he was working on Mission Impossible: Ghost Protocol. Tom's girls paid him a visit on the set, and he took advantage of a break from work to join them for a fun day out at the city's science museum.
