Mischa Barton Does Not Look Happy Leaving A Hollywood Hotspot!

Why the long face, lady??

Former OC star Mischa Barton was spotted leaving a Hollywood hotspot on Tuesday night.

Sporting an updo and some stripes, the actress looked a little glum, and totes ready for bed, as she stepped into her car and drove away. Guess that’s what a late night out will do to ya!

But it seems Mischa made sure to document her outfit prior to her departure and shared an Instagram photo with the caption, “Summer Nights.”

Ch-ch-check it out (below)!

She may have dissed The Bling Ring last week, but at least she got one thing right.

Summer nights truly are wonderful!
