Christina Aguilera loves showing off her cleavage and prefers to have a fuller figure

Speaking to Lucky magazine's October issue about her new fuller figure, she said: "Actually, the challenge I've always had is being too thin, so I love that now I have a booty, and obviously I love showing my cleavage."

Christina - who had Max with her ex-husband Jordan Bratman - also urged other curvaceous women to be proud of their bodies.

The 31-year-old singer - who is dating production assistant Matt Rutler - added: "Hey, if you can work it and you can own it, that confidence is going to shine through."

As well as her singing and acting talents, Christina is also a judge on the US version of pop star search show 'The Voice' but she is returning to her musical roots by releasing a new album later this year.

She told fans: "If you love 'Fighter', you're going to love my new album. As a woman in my 30s, I've been uncovering my independence, and it's been really fun to explore in the new songs."
