Christina Aguilera wants to record a duet with Blake Shelton.

The 'Beautiful' hitmaker is keen to work with the country singer - her fellow coach on the US version of 'The Voice - and wants them to collaborate on a new song together.

She tweeted him: ''@blakeshelton Now we need to team up for a country duet Blake!! I''m down!! Let''s go! (sic)''

As well as wanting to team up with Blake, Christina recently recorded a duet with another 'Voice' mentor, Cee Lo Green.

The 'Fighter' singer has already recorded her part of the track, with Cee Le preparing to enter the studio to set down his vocals.

However, the 'Forget You' hitmaker - who previously collaborated on 'Nasty' with the singer, which surfaced last year but was recorded long before they worked on 'The Voice' together - refused to give away too much about the song because it may share its title with Christina's forthcoming album.

He said: ''It's a song for her album. I won't disclose the title, because it could possibly be a working title.

''You know, but we've talked about it amongst ourselves and I'm gonna go in on it and work it out. It'll be the second song we've done.''
