Kareena Kapoor, who keeps entertaining us with different shades of acting in each of her movies, has now for the first time tasted the age-old dance of cinema - mujra - the classic Bollywood item number and something which every actresses dreams to do at some point of their career.

The hottie said to have done a mujra song for Shriram Raghavan's 'Agent Vinod', featuring her beau Saif Ali Khan in lead. The song has been choreographed by Saroj Khan while Manish Malhotra has done the styling for Kareena. Shot recently, the track features a gorgeous Kareena in bright red attire, with loosely tied hair.

According to unit sources, Kareena, who is not a trained kathak dancer, had a tough time in perfecting her steps. It seems she had shot for the song sequence for nearly 22 hours. At the end of which, she had bruises over her hands and knees as the song involved many floor movements besides other dance steps.

But being a thorough professional, the beautiful Bebo managed it all and said to have given a fine performance, sources added.

'Agent Vinod', an action-spy flick, is slated to release this December 9th.
