Mischa Barton has had several nip and full-blown boob slips in the fug outfits that she’s so famous for wearing. So this latest story that she flashed a nip at a children’s charity event isn’t that surprising. Her rep denies it, saying that that no one can prove with a picture, but there are pictures of her nips hanging out that night, and there are multiple other pictures of Mischa flashing her assets. In May, 2006 she wore a dress with a see-through panel over her boobs so they were clearly visible. About a year later she wore a loose lacy top that was cut down to her navel and fell open to reveal her full left boob, with Mischa smiling and looking all too aware of what was happening.

Mischa Barton shocked guests at a children’s charity event by accidentally flashing one of her nipples.

The actress experienced her wardrobe malfunction at the Save the Children event at New York’s Lincoln Centre - where guests included former US President George Bush Sr - last Thursday night.

One onlooker said: “Mischa was wearing a sparkly yellow dress and one of her nipples was blatantly showing! It was so not appropriate for Save the Children.”

A representative for the 21-year-old actress denies she bared her boob, saying: “It didn’t happen, because if it did, there would be a photo.”

Mischa Barton is moving along at a decent pace with her career. IMDB has her appearing in 4 movies yet to come out this year, and another 3 next year. She was just announced as joining the cast of a thriller, Walled In, which will begin shooting in Canada in late October.

Here are pictures of Mischa on the night in question in a typically ugly sparkly dress. You can see the tops of her nips through the top, so it’s not that much of a stretch to think that her dress sagged at some point that night and revealed the whole thing.

Thanks to Splash News for the first two pictures. The others from that night are from PRPhotos, and the last images are of Mischa’s earlier boob slips, thanks to WWTDD and The Bastardly.
