Guess Who: This Bollywood actor ditched his girlfriend to have a fling with a newbie!

We came across this interesting blind item on SpotboyE.com which had our grey cells working overtime. Can you guess who they are talking about? Read and figure out. Tell us in the comments section below...

"The story goes that this actor who is supposed to be oh-so-loyal types has suddenly attained wings. It's just that his girlfriend does not know much about what he's doing behind her back.
This guy recently developed a strong affinity for a star's daughter and the two are believed to have had a roll in the hay. Logon ka kaam hai kehna, and one of them has also told us that their force of attraction was so strong in magnitude that once they even  couldn't refrain kissing in public.
Neither of the two felt guilty when it was all over, and the guy in question even went back to his girlfriend as if he was as clean as he was when he first met her. The sinners haven't sinned again, though.
Can anybody tell us if the word 'loyalty' has been eliminated from the dictionaries?
The sad part of this interlude is that the girlfriend hasn't had even a whiff of the actor's kaarnamein.
Let it be a secret."
