Mischa Barton's fashion sense has come a long way in recent months, and wow, she's looking fit and fabulous.

The former OC actress, wearing black tights and short shorts, hit up the Music Box Theatre in Hollywood to catch Morrissey in concert.

The leggy actress wasn't the only celebrity in attendance. Showing off her slender post-baby bod in an all-black ensemble paired with killer boots, Kimberly Stewart also enjoyed the show and took a night off from watching 3-month-old daughter Delilah. Perhaps the baby was home with daddy Benicio Del Toro?

Girls just wanna have fun!



Let's face it, in this town, when you're skinny, you're usually happy -- and if you've lost weight because you're on a "divorce diet," you're probably still happy that at least one good thing came out of your failed marriage.

But in the case of Mischa Barton, who isn't in the throws of a messy breakup, her weight loss hasn't put a smile on her face. Or maybe it's just the paparazzi who make her frown?

Whatever the case, Ms. Barton and her lovely, well-defined cheekbones, looked spectacular last night as she left dinner on Sunset Plaza with a friend. Now if she'd just smile ...

Mischa Barton has surfaced in a new photo shoot for Tyler Shields. The pics show her posing with a very raw-looking steak. Yum!

In a largely punctuation-free post on his site, Shields said, "So one day out of the blue I start getting emails with the subject 'Mischa Barton' Upon opening the emails I realize they are from her fan club in Brazil they were asking me to shoot her ... She was amazing to work with and I cant wait to do it again."

See more bloody good pics after the jump!

Mischa Barton showed off her eccentric style at the Nice Airport Friday after she touched down in France to attend the Cannes Film Festival.

The O.C. star put a new spin French navy chic, wearing a boat-necked, red-striped sailor shirt with bright red jeans and ... well, HUGE red-rimmed glasses!

Does this look get a oui, oui or a non, non?

Last night Mischa Barton and a very excited female friend hit the Hollywood club scene, and it appears as though the former OC actress went with the age old trick of stepping out with a pal who isn't as blessed in the looks department.

I mean, when Mischa's on her own, is she still a 10?

The former OC starlet didn't have much to say to photogs, but it seems like she's trying to get her life and career back on track these days, as she's snagged roles in a handful of B movies due out this year...

The former O.C. starlet turns 25 today - happy birthday, girl!

And where is Mischa Barton celebrating her b-day? At a photo call for her film You and I (about two teenage girls who fall in love at a t.A.T.u concert) in Moscow. Party on!

Meanwhile, there's an online report circulating that Mischa is interested in joining Dancing With the Stars. Think that's a smart move for the actress?

Or is she the most stylish starlet in Hollywood? Maybe on Opposite Day! Former O.C. beauty Mischa Barton and her troublesome Cadillac stopped off in Silver Lake on Tuesday and we can't help but compliment her, uh, funky sunglasses. And what a sexy pair of--ugh, forget it. Is this outfit ridic or what? I mean, really!

And is that the same jacket she wore while playing a hooker? Yikes!
