A leaked version of Britney Spears singing Lady GaGa's hit single, Telephone has been proved to be authentic after the track hit the internet over the weekend.
There had been some doubt to whether it was Spears on the heavily auto-tuned demo, but producer Rodney 'Darkchild' Jenkins has now confirmed that Britney did record the track.
It is thought that GaGa wrote Telephone for Britney's Circus LP before she hit the big time herself but the Womanizer hit maker never managed to finish recording her version of the song, leaving Lady G to release the track with Beyonce.
Darkchild confirmed the leaked demo was Britney over Twitter, posting: "As ya'll know, it's been an overwhelming day today. I want to say to all the people on Twitter, all Britney's fans, all the Darkchild fans, I was caught off guard last night with this 'Telephone' leak of Britney,"
"I've been asked to leak the version, and I haven't leaked the version, and then last night, there was a version leaked. I really don't know who leaked the version. It was an early demo stage of the version."
He added: "It wasn't even a mixed version. I would never leak something without Britney's approval, without Larry Rudolph, without Jive Records,"
The producer also revealed Britney's manager wants him to work on some new material with the singer stating: "Larry Rudolph, Britney Spears' manager, came to my house...we had an incredible conversation about Britney Spears' new album."

He continued: "We talked about the direction of her album, he gave me some insight into the direction and he wants me to work on stuff for the album…I think the fans deserve it, I think Britney deserves it and I can't wait to get back into the studio with Britney."
Darkchild added: "I'm gonna give it my all to deliver something that's crazy, crazy amazing for Britney."
