Ever since she left The OC, Mischa Barton had been having a tough time finding the right role to take. In a recent announcement, Barton is searching no more - and celebrated by giving paparazzi a full frontal view after a “wardrobe malfunction” on Thursday night (May 17).

Mischa has just announced that she is set to appear alongside Rupert Everett in the new St Trinian’s movie.

The 21-year-old will return to the classroom playing J.J. French in the new comedy about the antics of students at an all-girl’s boarding school.

In London after the signing, Barton emerged from her limo for an evening at The Berkeley Hotel’s Boujis nightclub, in Knightsbridge.

According to Metro reports, “she was soon left red-faced as her delicate lace halter-neck top failed her.”

From the pictures, it looks as if nipple-taping was to blame, as her top gaped open exposing her left breast to all.

Barton becomes the second fashion victim of the double-sided sticky tape this week, as Cameron Diaz was also embarrassed after she came undone on the Ellen DeGeneres show.

Enjoy the oh-so-talked-about pictures of Mischa’s mishap - the first few are a bit explicit so click with caution!
