Mischa Barton Gets Detained By Airport Security

Mischa Barton tries to smuggle an energy drink into an LAX airport terminal on Tuesday in Los Angeles. But at one of the checkpoints, she was stopped and detained for a little while by airport security. Tsk, tsk!

Jetsetting Mischa should know that you’re not allowed to carry-on liquids unless it’s in a 3 oz. sized container or smaller!!!

Ms. Barton was accompanied by her photographer mom, Nuala Quinn, and her pet pooch Ziggy.
