Christina Aguilera and Adam Levine have recorded a duet together.
The singer and the Maroon 5 frontman are set to unveil the track, 'Moves Like Jagger', on talent show 'The Voice' - in which they are both judges - on Tuesday (21.06.11).
Adam explained it was "great" working with the 30-year-old beauty - and he admitted he's looking forward to debuting the song.
He said: "We are excited to perform it for our fans on 'The Voice' this Tuesday and on the road this summer.
"The guys and I recorded this track in Los Angeles last month and it was great getting to work with Christina on it as well."
Adam recently admitted the pair - who sit alongside Cee Lo Green and Blake Shelton on the TV show's panel - row "like brother and sister" on the programme.
Adam said: "They fabricate a lot of that - a lot of that's reality television fodder. She's fine, we bicker like brother and sister."
