She is not Aaradhya...this was a pic which got viral on internet long back when Aaradhya would be just weeks old... I agree with Lathaviswa...Bachhans are taking great care so that no one captures her picture!!
To know if she is Aaradhya or not we need to analyze if Aishwarya looks like this not now! Nah..don't think so ..:confused2:
It's her brother's baby....I'm not sure, but I think this picture's been discussed somewhere in the Movies forum....
