Christina Aguilera has increased respect for single mothers since she split from husband Jordan Bratman.

The 29-year-old pop star - who has a two-year-old son Max with the music executive - now realises how tough it is to care for a child alone since she separated from Jordan in October.

She said: "My focus first and foremost is my son Max. More power to single moms and those out there doing it."

She added to talk show host Ellen Degeneres: "At the end of the day, he's the love of my life. I adore him and he's such a character and he's so happy and that's what's most important."

Christina is managing to juggle all her responsibilities as a parent and successful singer and actress, but now builds her daily life around the tot and makes sure she is at home every night to sing him lullabies in bed.

She told TV host Jay Leno: "It's hard just even being a working mom and trying to balance and juggle everything on your plate.

"But I like to be the first thing [my son Max] wakes up to in the morning and the last thing he goes to bed at night seeing, and singing him his lullabies before bed. It means the world to me to be able to do that."

Although she was raised by just her mother Shelly following her parents' divorce, she wants to make sure Max's upbringing is less chaotic.

She added: "I grew up in a very chaotic household when I was younger so I want to make sure to instill in him a lot of love."
