We spotted former "O.C." star Mischa Barton on a beach in Miami today. She relaxed on a lounge chair with a male friend and wore a black bikini, white sunglasses, and a large heart necklace. She carried a map print bag.
Mischa fell off the radar in recent years. After quitting "The O.C." she starred in the failed series "The Beautiful Life" in 2009.
She will appear in the upcoming films "Apartment 1303 3D" and "Into the Darkness."
