Hot Mallika getting cold?

Summer's here and both Pepsi and Coke are stepping up their campaigns with the biggest names in the business.

After Shah Rukh, Aishwarya and Aamir, now 'hot' Mallika Sherawat, has joined the list of cold drink ambassadors.

So will Mallika send the cash registers ringing for Pepsi, which has signed her up for its Seven Up brand?

We'll wait and see, but Fido Dido had better watch out!
