London:  Singer Christina Aguilera says her son Max is the "love of her life" and that her happiness depends on him. Aguilera has three-old Max with ex-husband Jordan Bratman.

"The best thing about being a mom is seeing my son Max smile every day. He is truly the love of my life and knowing that he's happy makes me happy," a website quoted 30-year-old as saying.

"A great deal of my happiness revolves around my son. The best days are when I just get to lay in bed with him, get cosy in the blankets and watch a classic Disney movie like 'Alice in Wonderland'," she added.
