Mischa Barton showed some junk in the trunk not too long ago when she was spotted wearing high-waist yellow jeans. The actress is showing off a little plumpness again - only this time it's in a different spot.

Mischa wore a white satin chiffon Marchesa gown with a ruffled off-the-shoulder neckline at the "2010 amfAR's Cinema Against AIDS" near Cannes yesterday. Cleavage, much?

Ex-boyfriend Brandon Davis recently called her "one of the fattest people on the planet." In a post on Twitter, he wrote: "Omg. Just realized my ex turned in to 1 of the fattest people on the planet. I'm gonna start dating plus size models. Not! Mischa the Hefer (sic)."

What do you think of Mischa's fuller figure?
