Aishwarya Rai is a great mother and we all know that how much she loves Aaradhya. Baby Aaradhya is 4 years old now but still Aishwarya carrying her in the photos wherever they spotted. Now, the ravishing actress reveals why," At one point when we were walking, she was in a great mood, even as people clicked pictures. She was laughing and saying something funny. But, when people started caving in, I had to pick her up because she is too tiny to handle all that. I had to steer my way through the crowd. It is just a protective instinct, I keep her close."
