Christina Aguilera hopes her curvy figure will "empower" women. The 31-year-old "Your Body" singer - who has attracted a huge amount of publicity for her current weight - insists she is comfortable in her own skin and hopes her struggle will "empower" other women.

"I'm always in support of someone who is willing and comfortable in their own skin enough to embrace it. Embracing your body is so important, especially as a woman. In this business we are so analysed and judged. It's wonderful to be in a position and have that side of myself that I can latch on to and empower other women. The older you get, the more important it is to embrace your body and your sexuality."

The Voice judge also opened up about her four-year-old son Max and the pressures of juggling motherhood and her career: "I can wear different hats - for example, the artist hat. When I'm on that stage and I've been in the wardrobe getting dressed up to play a character, I am living out a specific moment in a song. That hat is very different to the one I wear when I go home at night and I tuck my son in and I'm singing Twinkle, Twinkle, Little Star. It's a crazy thing, it's an interesting road he has ahead of him, but as I said, I try to keep all the different hats I wear very different so that Mummy's hat is very different from party hat. It's a real balancing act for me."
