Lady Gaga wants to duet with Britney Spears.
The singer tweeted her fellow US star saying the time is right for them to collaborate, after the 'Work Bitch' hitmaker said she wanted to record a song with Gaga.
During a live fan chat to promote her new album, 'Britney Jean', the star said: "I would do a duet with Lady Gaga. I think that would be a lot of fun. I think she's very different and interesting and intricate."
Responding to the answer, Gaga later tweeted 32-year-old saying: "@britneyspears lets do this bitch its time [sic]."
The 27-year-old headlined Capital FM's Jingle Bell Ball at The O2 in London over the weekend in support of her chart-topping album 'ARTPOP'.
Meanwhile, Britney's eighth studio record has just become her lowest charting album in the UK, debuting at number 34.
Lady Gaga previously teamed up with fellow US diva Beyonce on the 2010 hit 'Telephone' but the pair ended up falling out after the 'Single Ladies' hitmaker called her a "selfish egomaniac."
However, the pop stars are reportedly putting their differences aside to join Katy Perry as the headline acts for next month's Grammy Awards in Los Angeles.
