BRANDON DAVIS: 'I'M NOT TO BLAME FOR FAT MISCHA BARTON TWEET'

Socialite Brandon Davis has fired back at criticism he received for poking fun at ex-girlfriend Mischa Barton's weight woes via Twitter.com, insisting the comments were not his.

The actress was devastated after reading what appeared to be a cruel 'tweet' from her ex, but Davis claims he doesn't even have a Twitter.com account - and the taunting had nothing to do with him.

The post read, "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)."

Outraged Davis has since reached out to In Touch magazine in a bid to clear his name.

He tells the publication, "I would never say anything nasty about Mischa, especially about her weight. I am p**sed that someone stole my identity and started Twittering things."
