Troubled star Mischa Barton was reportedly seen close to tears at a showbiz party after a former lover called her "one of the fattest people on the planet".
The former OC star was spotted by oil heir Brandon Davis at a magazine's anniversary bash in Los Angeles on Wednesday, who aimed the cruel comments at her, reported New York Daily News.
"OMG (oh my god). Just realised my ex turned in to 1 of the fattest people on the planet. I'm gonna start dating plus size models. Not! Mischa the Hefer (sic)," he wrote on his Twitter page.
And the actress was visibly upset by the jibes.
"She was chain-smoking the entire night. Mischa was never without a cigarette in her hand - and a (scowl) on her face," said an onlooker.
