Britney Spears has been hard at work on her Femme Fatale tour, so it's no wonder that she needed to take a break and see the sights overseas!

First stop? Checking out fashion at the Kira Plastinina Design Studio on Saturday in Moscow, Russia, the second stop on the European leg of her tour.

The "I Wanna Go" singer drank tea with 19-year-old designer Kira before checking out the showroom and factory.

Brit Brit had an amazing time in Russia on stage as well. She Tweeted, "Love you Moscow!" and wrote to a fan, "Ur Welcome - had so much fun!" after Saturday night's show.

A full day of fashion followed by her own awesome concert? Sounds like the perfect day to us!

We caught up with Katie Holmes in Beverly Hills on Monday, where the star ran errands.

Katie was, as always, classy, but casual. She wore her hair down, with a camel-colored sweater, boots and belt.

Holmes is returning to her TV roots with an upcoming guest star role on How I Met Your Mother -- she'll play the character Slutty Pumpkin for the Halloween episode. Interesting!

This is what Ashley Tisdale looks like after exercising?!

The Disney darling kept up her usual routine Sunday by hitting up her gym in West Hollywood. She emerged from Equinox looking picture perfect in a cheetah print zip-up, skinny jeans and black Ugg boots.

And she had time to put a cute braid in her hair? Color us jealous.

The Tis is so happy taking classes like pilates that she raved about her fitness center on Twitter. "Bc I love my gym so much...Happy anniversary to everyone at @Equinox. Lovin the new purple shirts! #Happy20thEquinox," she wrote last week.

Dedicated and super nice!

Bravo's Millionaire Matchmaker Patti Stanger made waves with her Sunday night appearance on Andy Cohen's talk show, Watch What Happens Live.

In the Season 5 premiere, Stanger addressed callers flippantly, ordering one woman to read her book and watch her DVDs, and then made things especially awkward when a gay man Skyped the show with a question.

“You’re very handsome," Stanger said. "I thought you were straight. That’s a compliment.”

Patti's comments seemed to offend the audience, which got so quiet that Cohen remarked how silent the crowd was. "I'm uncomfortable," he said.

Cohen also had to stand up for himself to Stanger, who argued that gay men were less likely than straight people to be monogamous. "There’s no curbing the gay," she said. "I’ve tried to curb you people. I’ve decided to throw in the towel and just say, ‘Do what you want.'"

Grey's Anatomy hottie Kate Walsh is back on the market ... in terms of real estate anyway!

Walsh has put her Spanish-style Los Angeles mansion for sale again at $3.995 million -- she paid $4.75 million for the 5,940-square-foot house in 2007.

The four-bedroom, four-and-a-half bathroom home was built in 1928. Walsh first put it on the market in May 2010, then took it off five months later.

Features include gorgeous stand-alone tubs, walk-in closets, pool, guest house, gym and more.

We get the whole comfy thing, but Jessica Alba's baggy gray pants are not our favorite!

The mommy of two ran errands in Beverly Hills with her husband Cash Warren, and it looks like the 30-year-old star is having a rough day.

We prefer seeing the Spy Kids 4 actress in form-fitting outfits ... but even fashionable starlets need a break every once in awhile!

Cute new couple alert!

Jordin Sparks stepped out Sunday night looking skinnier than ever in a sheer-meets-leather LBD, and she had an interesting date by her side ... Jason Derulo!

The two looked very cozy as they hit up Philippe Chow in Hollywood to belatedly celebrate Jason's 22nd birthday.

A few days earlier, the "Tattoo" singer wished her man a happy b-day on Twitter, to which Jason replied, "thx LOVE." Jordin quickly wrote back, "Will you get back to the states already?? lol :P"

Hello, flirty!

But on his way into dinner, Jason had some interesting (and not-so-sexy!) things to tell our X17 photogs -- like how he would eat an ant for dinner. Check out some of his crazy comments in the video below.
