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

The pop star - who shot to fame after starring on the 'The Mickey Mouse Club' in 1993 - has had a more curvaceous body in recent years since the birth of her son Max in January 2008 but she insists she enjoys having a more bountiful body to work with.

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.''
