No Doubt are back together and will be hitting Gossip Girl's Upper East Side, but will their new song be a hit with Blair and co?

No Doubt are kicking off their come-back with a cameo appearance on Gossip Girl and we can't wait to see Gwen rocking out with the GG crew!

Gwen and the boys star as 80's band 'Snow Doubt' and play a cover of Adam Ant's hit Stand And Deliver.

Airing on 11th May in America, the episode is a starting point for the Gossip Girl spin-off show, all about Lily Van Der Woodsen's wild, rock 'n' roll teenage years.

Executive Producer Josh Schwartz said: "It's about Serena's mom Lily growing up in L.A. in the '80s. And the pilot will air as a series of flashbacks inside the May 11 episode of Gossip Girl, " Schwartz said. "We've shot it all, and it all looks great."
