Dianna Agron, Cory Monteith, and Mark Salling were among the Glee castmembers that arrived in London this afternoon ahead of their appearance on The X Factor this weekend. Mark stuck his tongue out at photographers as he walked through the airport with Dianna, Kevin McHale and Jenna Ushkowitz. New addition to the cast Chord Overstreet and Naya Rivera, who plays cheerleader Santana, followed close behind their castmates. Next year they'll be back in the UK to perform songs that they've sung in the show live on stage, in a recently announced tour which will take place in Summer 2011.
