They form a very unlikely pair.

We're talking about Mallika Sherawat [Images] and Nana Patekar, both outspoken people who never fail to make headlines.

The two star together in the much anticipated Christmas release (December 20), Welcome, that also stars Akshay Kumar [Images], Katrina Kaif [Images], Anil Kapoor [Images] and Paresh Rawal [Images].

While the Kiya Kiya song, currently on air, sees both Anil Kapoor and Patekar wooing Mallika, here's a sneak peek at what the two look like together.
