PICS: X Files stars David Duchovny and Gillian Anderson lock lips on stage during his debut album performance

New York - They starred together on The X Files, but on Tuesday night David Duchovny and Gillian Anderson played like they were on The X Factor.

The X Files stars sang together onstage in New York City, performing Neil Young's Helpless on the day Duchovny released his first album. The Golden Globe-winning actor sang lead while Anderson harmonised with his background singers and band.

"Can we play some real music please?" Anderson joked, joining in when Duchovny and his band returned for an encore performance at The Cutting Room.

"Is there anything you're in the mood for perhaps?" the actor asked the actress, who replied, "Do you guys know Helpless?"

Duchovny gave Anderson a light kiss on the lips after the performance and whispered in her ear as she left the stage.
