Beyoncé And Tina Turner - Duet at Grammy Awards

An insider told People magazine: ´We don´t know what they´ll be singing yet, but it is sure to be an amazing performance´.

Beyoncé Knowles and Tina Turner are to duet together at the Grammy Awards. The 'Crazy In Love' star and music legend Tina will reportedly join forces at the prestigious awards ceremony on February 10.

An insider told People magazine: "We don't know what they'll be singing yet, but it is sure to be an amazing performance." Beyoncé, 26, has never made a secret of her admiration for 'Simply The Best' singer Tina, and even performed her hit 'Proud Mary' during a tribute to the star in 2005.

Meanwhile, The Writers Guild of America - currently on strike over a pay dispute - announced this week they will not picket outside the Grammy Awards at Los Angeles' Staples Center, clearing the way for stars to safely attend the show.

Foo Fighters frontman Dave Grohl is so far the only artist to have publicly agreed to attend the ceremony, which is broadcast live on television. Meanwhile, Britney Spears - who was ridiculed for her comeback performance of 'Gimme More' at the MTV Video Music Awards last year - will not be
invited to the Grammys. An insider confirmed: "Britney is banned from the building."
