As previously announced, Gwen Stefani and No Doubt will perform “Stand And Deliver” on the May 11 episode of The CW’s Gossip Girl, but some exciting new details are emerging about the band’s big television appearance.

According to The New York Post, No Doubt will appear as the fictional band Snowed Out on the eagerly-awaited flashback episode intended to introduce G.G fans to the main characters on the show’s upcoming spin-off. The flashback episode is set in 1983 Los Angeles and will follow a young Lily van der Woodsen (nee Rhodes) played by Brittany Snow.

“We’ve done plenty of television performances, as ourselves doing our own songs, but ‘Gossip Girl’ was a new situation,” No Doubt guitarist Tom Dumont remarks in a new interview with The Post. “We’re kind of like actors in the sense that we’re doing something within a drama on television.”

No Doubt rocks Gossip Girl on Monday, May 11 at 9 p.m. on The CW.
