The secret behind the chemistry between Vidya Balan and Madhavan in the Airtel ads is out. It is Madhavan's two-year-old son Vedant. The child bonded so beautifully with Vidya on the sets of Guru that she became a part of Madhavan and his wife Sarita's inner circle. In fact the cell phone company has now decided to put out a series of ads featuring Madhavan and Vidya as a couple connecting emotionally on the phone.
Curiously Madhavan and Vidya have hardly shot together for these ads about love and togetherness. 'We've just done one shot together. The rest has been shot with the two of us separately. Its strange people have noticed so much chemistry between us when we aren't even together in the ad. My wife Sarita loves the ad. She thinks Vidya is better than me in the ad. But then she's my harshest critic. All three of us Sarita, Vedant and I adore Vidya.'
