Mischa Barton was reportedly “visibly upset” after her ex-boyfriend Brandon Davis (AKA Fat Elvis) called her “one of the fattest people on the planet” in a Twitter post this week.

“Omg (oh my God). Just realized 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),” the oil heir wrote in a mean-spirited Tweet.

Davis aimed the cruel comments at former The OC star after spotting her at Nylon Magazine’s 11th Anniversary Bash in Los Angeles.
