Yesterday Mischa Barton didn't have time to stop and pose for a self-portrait after leaving the gym, so she simply took one in traffic while driving her caddy down Sunset Boulevard!

Sure, it's technically not illegal (yet) to do a cell phone photo shoot while driving, but considering Mischa's history with cars, perhaps she should just keep her hands and eyes on the road!

But maybe she was just so thrilled with her 80s-style workout gear that she wanted to show all her Facebook friends ASAP. Either that or she wanted to prove to the cyber-verse that she's actually working out.
