London: Pop star Christina Aguilera whose figure has changed considerably after giving birth to her son says she doesn't care what people say about her weight because she is happy with her look and even her boyfriend likes her the way she is.

The 31-year-old singer and mentor on US TV show 'The Voice', who has come under fire for her fuller figure, said she and her boyfriend Matt Rutler are happy with the way she is, a website reported.

"I have a boyfriend that loves my body. I love my body, my son is healthy and happy and that is all that matters.

"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," she said.

Aguilera, who has son Max Liron with ex-husband Jordan Bratman, said being confident in herself has been key to her success.

"You have got to be a strong, powerful, very confident woman. Being in a position to coach these young women, I am happy to be able to share that with them and share my highs and lows. Being on the show, it's a very good outlet," she added.
