We're not sure what exactly Kim and Kourtney Kardashian were up to this afternoon on Robertson Blvd in West Hollywood, but it seems like it's related to expanding their family's already huge fashion empire!

Kim tweeted, "I'm in an extra good mood right now! Meeting up with @KourtneyKardash. Were doing something so exciting! #DashLA". Think they're looking to open a Dash boutique somewhere on this side of the hill? Their other store is in Calabasas, which is a long haul for all of the Beverly Hills and Hollywood shoppers...

We don't want to give her a hard time (after all, she's due to pop pretty soon!), but what on earth was Hilary Duff wearing yesterday? The top wasn't so bad, but that skirt? It looks like something from Abercromie & Fitch circa 2000 ... eeks!

Moving on from her questionable outfit, is sounds like the pregnant starlet had a lovely Valentine's Day with hubby Mike Comrie. Yesterday the former Lizzie McGuire actress tweeted, "This girl got breakie in bed this morning! Such a sweet surprise! Happy love day tweet hearts! Hope your day started out as good as mine!"

So sweet!

Taylor Armstrong stopped by The Grove shopping center in LA for an interview with Extra to talk about her abusive past with now-deceased husband Russell ... and also to promote her new book, Hiding From Reality.

The mother of one has been very vocal about her tumultuous relationship with Russell on the Real Housewives of Beverly Hills three-part reunion special.

One of the personal tidbits that Ms. Armstrong shared on the Bravo reunion show was an incident in which Russell allegedly forced Taylor to take a polygraph test to prove she had been faithful.

George Clooney, who earned an Oscar nod for The Descendants, is opening up about Ocean's Eleven co-star and buddy Brad Pitt ... and putting the brakes on drinking alcohol.

When asked about his friendship with Pitt, Clooney tells the Hollywood Reporter:

“Brad is one of the great guys. We’re good friends, but it’s different from what people think, meaning we don’t spend a lot of time together. He has been to my home in Como; we motorcycle together. But until recently, I hadn’t seen Brad in a year.”

As for his troubles with alcohol, the 50-year-old actor adds:

"I drink at times too much. I do enjoy drinking, and there have been times in my life when it’s crossed the line from being fun to having to drink late at night for absolutely no reason. So what I do is, I stop. I haven’t had a drink since New Year’s Eve.”

Love the honesty, George!

Looks like things are getting serious with Ivana Trump and her new boyfriend, Antonio Zequila!

The lovebirds were snapped kissing on the beach in St. Barth yesterday, and we're guessing they'll be staying there through next week, as Ivana's 63rd birthday is on Monday. We love the fact that the cougar/grandmother of three isn't afraid to bare her bikini bod in front of the cameras!

Blake Lively has obtained a restraining order against a male fan who has been "lurking around" the New York set of Gossip Girl.

According to court documents obtained by ET, a man named Sergie Mifle has claimed to have a "metaphysical or spiritual" connection with the actress, and on several occasions he came to the set to "help [her] heal." Lively stated that she is "afraid for [her] safety", and it was also revealed that Mifle attempted to contact her mother.

The restraining order requires Mifle must stay at least 100 meters away from Lively, her mother and the Gossip Girl set.

Kim Kardashian and a gal pal were spotted leaving the gym in Los Angeles today, and it sounds like the reality TV starlet wasn't all that motivated to get her booty out of bed!

"Was a little lazy in bootcamp today but at least I went," she tweeted. "Lol I will make up for it later today!" Hey, at least she's honest! And given how much time she spends working on her fitness, we think she's allowed to lighten her load every once in a while, right?
