Troubled thesp Mischa Barton‘s booze fueled tummy trouble..
Reportedly, the former OC actress who’s been struggling with sobriety had a very rough night over the weekend.
Barton rolled into LA hotspot Bar Marmont Saturday, sans enablers, and looked "totally out of it," a spywitness told a NY tab.
"A few minutes after she comes in, she runs outside and vomits everywhere.
"And then she went back inside and hung out for the rest of the night."
Just another Misch mash-up.
