Confident Christina proudly parades her fuller figure... in a VERY tight purple dress at AMA nominations

If there was any doubt that Christina Aguilera has well and truly embraced her fuller figure, then look no further.

The 31-year-old singer put in a very confident turn on Tuesday as she poured (and squeezed) her very generous proportions into a form-fitting body contour dress.

Needless to say, Christina - with dress pulled taut over her bust and bottom - delivered an eye-catching look as she arrived to present the American Music Award nominations at press conference in Los Angeles.

 The Beautiful songstress was in full-on performance mode for the photographers - sticking out her rounded derriere, putting her hands on hips and twirling round for her over-the-shoulder shot in a series of moves that threatened derail Kim Kardashian's reputation as having the most famous bottom in Hollywood.

The Voice judge completed her style with a pair of sky-high silver heels, fake eyelashes along with her newly-dyed pink and purple-tipped blonde tresses.

 Christina, a mother of one, had slathered it on in abundance, particularity so over her legs - which appeared to be a darker shade than the rest of her body.

Aguilera, who announced the AMA nominees on Tuesday, was the first performer to be announced for the live show, which takes place next month.

R&B star Rihanna and rapper Nicki Minaj led nominations for the American Music Awards with four apiece, edging out stiff competition from pop sensations Justin Bieber and One Direction.
