Mischa Barton says that she is single for the first time in her life, and that she wants to stop dating immature men. The O.C. star says that her next boyfriend will be funny and intellectual. She told Elle magazine, "I like an intellectual guy, because I love to read. If they like movies, books and music, we're pretty alright. And I'd like someone who's mature. God, I can't take another immature person!" Barton, who is not yet 21, recently split with her rocker boyfriend Cisco Adler. The breakup came last February, after photographs of Adler with Paris Hilton surfaced on the internet. Barton also dated oil heir Brandon Davis for more than a year. |
