Beyonce Knowles is set to perform at next month's Grammys with none other than Tina Turner.

The twosome will inject some wow-factor into this year's Grammy awards ceremony in Los Angeles, as Beyonce joins 68-year-old superstar Tina on stage in a sensational music-style comeback.

Tina, whose singing career has spanned three decades, retired back in 2000 - but is now geared up for a revival.

Beyonce has long been a fan of Tina's, and even did a live performance of her song Proud Mary, as a tribute to the mega diva at a concert back in 2005.

It's not known yet what songs the awe-inspiring pair will perform, but with the power of those two voices combined, it'll no doubt make for a show-stopping performance.

Tina Turner and Beyonce KnowlesLet's face it, Bey is pretty much a younger Tina, what with the big songs, show-stopping outfits and strutting stage routines.

In fact, so similar are they that we've delved a little deeper and compared the two divas in our Beyonce 'n' Tina gallery.
