Gossip Girl star Ed Westwick had to be rescued by his co-star and former flat mate Chace Crawford when he ended up in a fight with fellow Brit actor Toby Hemmingway. Ed and Toby squared each up to each other at former ‘N Sync star JC Chasez’s birthday bash at fancy Hollywood bar El Guapo Cantina on Saturday, but when the row escalated Chace had to step in and pull Toby off Ed. It’s not known what caused the fracas - maybe Ed refused to play the part of Joey Fatone when the DJ played Tearin’ Up My Heart?
