The 31-year-old singer addressed the issue of her changing shape while promoting TV show The Voice at the Langham Huntington hotel in California yesterday.

Speaking to the press, she said: 'I have a boyfriend that loves my body. I love my body, my son is healthy and happy and that is all that matters.'

She added: 'Women, we are definitely under a microscope and under massive scrutiny. As long as I am happy in my own skin, that is all that is all the confirmation I need.'

Wearing a plunging Thomas Wylde leopard print maxi dress, Christina explained that confidence played a huge part in being a successful female music artist.

She said: 'You have got to be a strong, powerful, very confident woman.'

The singer, who has a three-year-old son with ex-husband Jordan Bratman, has been dating Matt Rutler since late 2010.
