Asin has been roped in to play Ajay Devgn's love interest in Rohit Shetty's next, Bol Bachchan.

The Ready actress has worked with Ajay in London Dreams.

A unit birdie tells us that Asin was keen to do Singham but as she didn't suit the part, Devgn had promised her that he would consider her for Bol Bachchan which he did.

Now that's a man of his word!

The film also stars Abhishek Bachchan with Genelia D'Souza paired opposite him.
