Says a source close to Kareena, "Though Kareena and Shahrukh haven't done any films together; after Asoka and Don, their chemistry has been sizzling. Bebo is also very fond of SRK. When Shahrukh, who plays a superstar in Billoo Barber, asked her to perform to a song with him, she agreed. Kareena is keeping dates aside and will soon be shooting for the song by next week.
Deepika Padukone is also being pencilled in for the song with SRK. Kareena and Deepika will be the two actresses playing themselves vying for Shahrukh's attention in the song." Billoo Barber is a story based on the friendship between two friends - one, a rich city slicker and the other, a poor villager. SRK plays a big star while Irrfan Khan plays a village barber.
The two are friends since their school days; who drifted apart only to meet years later. Tabu was initially considered for the lead opposite Irrfan but now Amisha Patel has been signed on. While Gulzar has penned the lyrics, the screenplay is by Mushtaq Sheikh and Manisha Korde.
