Abhishek wary of Ash-Hrithik's chemistry?

After DHOOM 2 and JODHAA AKBAR, GUZAARISH is Hrithik Roshan and Aishwarya Rai Bachchan's third film together. Both movies got a very good response from the audience and GUZAARISH promos too have caught huge eyeballs ever since they have been released. The duo set the frame on fire and keeps it sizzling each time.

And what we found out recently was that Abhishek Bachchan has noticed this chemistry too. Now wouldn't that be the reason he keeps dropping on the sets all the time?
