Ed Westwick's Bar Brawl With Toby Hemingway

Gossip Girl‘s resident bad boy Ed Westwick got into a fight with fellow British actor Toby Hemingway at former boybander J.C. Chasez‘s birthday party at the private Hollywood bar above El Guapo Cantina on Saturday night (August 8).

“Toby started choking Ed,” a source exclusively tells JustJared.com. “[Ed's co-star and former roommate] Chace Crawford had to pull them apart.”

Chace and Toby starred together in the 2006 horror flick, The Covenant.

Also in attendance: Milk screenwriter Dustin Lance Black.

Calls to Ed‘s rep were not immediately returned.

UPDATE: “There was no fight,” Ed‘s rep tells Just Jared. “Ed and Toby are friends and have been talking since the party.”
