Mischa Barton Forgot To Wear Her Underwear, Shows Off Her Tush [PHOTOS]

The star walked in a bridal fashion show.
I hate it when that happens.

Actress Mischa Barton was spotted dining on some Burger King and beer with an unidentified male yesterday in Ibiza, Spain.

Mischa and her paramour kissed several times during the meal. Aww. Young love.

As she finished up her lunch and gathered her luggage, she bent over in her very short pink dress, only to reveal she wasn’t wearing underwear! Oops.
