They were last seen together in "Paa". Now they are re-uniting on the small screen, even if it's just for a bit.

Yesterday, Vidya Balan shot at Film City with the Big B for "Kaun Banega Crorepati".

Dressed in a sexy blood-red sari on the lines of what Dimple Kapadia had worn in "Sagar", Vidya had a whale of a time getting quizzed by the legend and promoting her keenly awaited "The Dirty Picture", which releases worldwide on December 2.

The fun-filled episode (apparently to be telecast on November 10 on Sony TV) will also see Vidya and the Big B moving to the sensational "Ooh La La" track, which has taken the nation by storm.
