Gossip Girl star rock debacle.

Tiny diva Taylor Momsen has been working on a fall-back sideline gig just in case her career goes bellyup when GG is inevitably canceled.

Following in the footsteps of musical greats such as Joaquin Phoenix, Keanu Reeves and other actors-turned -rocker, Momsen is hitting the road with her band.

"It's really exciting - we're called The Reckless," Taylor enthused. "We're putting out our album this year and hopefully starting to tour around April."

"I do write it all 100 per cent myself. I'm the lead singer and I play guitar and I totally oversee it. It's a huge passion and totally important to me.

"It's really exciting and probably not what people are gonna expect."

Yeah, it is.
