Christina Aguilera wore a tight dress at the American Music Awards on Sunday night (20.11.11), which has sparked pregnancy rumours.

The singer performed 'Moves Like Jagger' with Maroon 5 frontman Adam Levine - who sits on the judging panel of TV talent show 'The Voice' with the blonde beauty - at the ceremony at the Nokia Theatre in Los Angeles, which led to a number of comments on blogs and social networking site twitter.

The mother-of-one sang in a tight figure-hugging white bandage dress, which she teamed with Christian Louboutin heels and a frizzy hairstyle.

It comes after Kelly Osbourne criticised the blonde singer in August during an episode of E!'s 'Fashion Police' in August.

She said: "Maybe she is just becoming the fat bitch she was born to be. I don't know. She was a **** to me. She called me fat for so many f***ing years. So you know what? F**k you! You're fat too."
