AceShowbiz - Formula One race ace Lewis Hamilton has made his pop debut on Christina Aguilera's new track Pipe.
The 33 year old, who dated another top singer - Nicole Scherzinger, can be heard singing a verse in the song, credited as XNDA.
Aguilera is refusing to confirm the identity of her mystery collaborator, but sources tell The Sun it's definitely Lewis, who has spent seven years trying to break into the music industry, working with heavyweights like Jay-Z and Kanye West.
Hamilton told reporters last year, "I've a lot of plans, a lot of things you'll see come together in the next couple of years."
He has also teamed up with British singer-songwriter Jess Glynne on new music.
"We talk every now and then and he's a really cool guy," she said. "I have been in the studio doing some music with him actually. He loves music and he's a really talented guy in all walks of life."
The Right Here singer remained vague over what material the pair might be bringing out, but insisted the end result would be worth waiting for.
"I know he's really into doing his own thing musically. And I know when he does release stuff you'll be in for a treat. I performed at one of the Formula One gigs and that's how we became friends," she smiled.
