Mischa learns the hard way about booze and drugs

Looks like there may be more than meets the eye to Mischa Barton's emergency hospital visit this weekend, with the starlet learning the hard way that alcohol and antibiotics don't always mix. At a barbecue on Sunday, Barton drank a "s**tload" of alcohol, says a source, while taking antibiotics after falling ill in Cannes. "Her face turned completely white, and she spent over 30 minutes in the bathroom," says a fellow partygoer. "It was really scary."
