Mischa! We definitely didn't forget about you -- or your 26th birthday tonight! Girl, you still so fly.

We first remember the beaut in her bit role in Sixth Sense as the puking, poisoned little ghost girl under a bed. Yep, I recall nightmares staring her circa my sixth grade days. But then she joined up on the phenomenally successful teen drama The O.C. as Marissa Cooper. Now I'll probably always refer to her as Marissa before I remember it's Mischa.

While we're talking about it, let's reminisce over Marissa's beautifully dramatic life in Newport with this strange, fan-made montage soundtracked by Seether (?!!):

OK, back to Mischa. She's got a great eye for style and even has started lending that talent to design a line of handbags. Check out the gallery below for some of our favorite Misch outfits!

What role do you best remember Mischa for? Did you ever root for her in The O.C.?
