Himesh Reshammiya's acting debut is getting more and more interesting.

The latest is that Mallika Sherawat is slated to play a vamp in Aap Ka Suroor. This will be her first negative role.

But apparently, her role will only be a cameo, lasting about ten minutes.

The lead heroine is a newcomer called Riaa.

Aap Ka Suroor, directed by first-timer Prashant Chadha, will release on June 29.
