London, Feb 22 : Her son is not the only reason Christina Aguilera is smiling these days, for adding to her joy are her 'amazing' pregnancy boobs.
The 27-year-old singer has been nursing son Max ever since she gave birth last month, and this has given her twin assets a boost.
She told chat host Ellen DeGeneres that her new cleavage was one of the changes pregnancy brought about in her body.
"I was just amazed by the whole process of being pregnant. It's unbelievable to see yourself grow like that. So my stomach was huge back then, and now my chest is huge!" The sun quoted her, as saying.
She also talked about her son Max, saying that she and hubby Jordan Bratman love watching their little one.
"To see the product of your love together is just incredible - my husband and I just can't stop staring at him," she said.
