Christina Aguilera in Herver Leger dress London - Arabstoday Curvy Christina Aguilera hits another bum fashion note as she spills out of her bandage dress. At the 2011 American Music Awards in Los Angeles Sunday, the singer joined Maroon 5 on stage during "Moves Like Jagger," clad in one of Herve Leger's curve-hugging bandage dresses, which she teamed with sky-high Christian Louboutin heels and a wildly frizzy hairstyle The figure hugging mini-dress was a little on the small, short and tight side for her curvier figure, but she didn't seem to mind as she flaunted it in all it's glory. As she was raised onto the stage mid-song on a glittery silver podium, Christina looked significantly heavier than the size four she has claimed to be. The songstress, her major cleavage and silver skin-tight mini instantly received backlash on blogs and Twitter, sparking speculation that the 30-year-old, who's already a mom to one, may be pregnant. Fans and critics in the cyber world aren't the only ones who've been slamming Aguilera for her fluctuating weight. In August, Kelly Osbourne had some choice words for the star on an episode of E! Fashion Police.
