Though Bipasha Basu and Karan Singh Grover have admitted that they are not dating each other, one can't help but notice the sizzling chemistry that the duo share whenever they put in an appearance together. While Bipasha being the senior actor has always done maximum talking, Karan came into his elements at the music launch of Alone yesterday night.

Dressed in a body hugging black shirt, Karan looked ready to kill while Bipasha looked hot in a pink coloured off shoulder evening gown. As the duo took to the stage, an over enthusiastic hostess couldn't keep her hands and eyes away from the handsome Karan. It's different story that she ended up proposing Bipasha, all in good spirit though.

The promoters of Alone who had hitherto used Bipasha's star power to publicise the movie decided to indulge in a new stunt to help grab more eyeballs for the film. And it was Karan whom they turned to this time around wisely drawing a marketing strategy that would result in Karan taking off his shirt to show the world his jaw-dropping perfect body. Karan boy, was ofcourse game.

Almost on cue, the hostess moved towards Karan and asked him if he could show everyone present how real his six packs are. Without flinching, Karan pulled up his shirt and let loose his perfect six pack washboard abs as lensmen went crazy clicking. Karan even slapped his abs vigorously just to prove they are not fake. Unfortunately, the actor didn't do a half monty much to the dismay of the photographers one of whom even requested Karan to pull his shirt further up only to be chided by the actor.

Bipasha meanwhile was all smiles and spontaneously remarked, "Karan's six packs are absolutely real and I can vouch for that."

Well, we are sure both Karan and Bipasha must be sharing a lot of fitness tips with each other these days.
