Singer and "The Voice" judge Christina Aguilera's appearance at the 2013 American Music Awards in Los Angeles has certainly hit back at the people who harshly criticized her full figure and fashion style at the awards show one year ago. Christina, 32, stunned the crowd with her slim figure in a white Maria Lucia Hohan gown that she wore on Sunday night, November 24, at the Nokia Theatre red carpet.

Simone Harouche, Ms Aguilera's stylist, expressed on Twitter how captivated she was with the singer's look at the event. "@JustJared: Christina Aguilera-AMAs 2013 @xtina brings some old school glamor to the red carpet! http://goo.gl/fb/R1yxi my girl killed it!" the stylist posted on her Twitter account @simoneharouche.

According to the HollywoodLife report, Christina Aguilera impressed with her old Hollywood glamour look of loose hair curls, thanks to celebrity hairstylist David Babaii, bright lipstick, Christian Louboutin shoes, Jimmy Choo bag, Lorraine Schwartz jewelry and the white dress with plunging neckline and side cut-outs.

The singer continued to wow the fans not only with her new slim look but with her powerful voice as well. Christina Aguilera slipped into a simple black dress and performed "Say Something" with A Great Big World on stage.

Fans showered Christina Aguilera with compliments on Twitter over her weight transformation. One tweet read "This is what I call PERFECTION" while another fan tweeted "Who invented the time machine that 2002 Christina Aguilera walked out of?!?"

Singer Kelly Clarkson praised Christina Aguilera for her vocal power at the awards show and not her looks. She posted on her Twitter account @kelly_clarkson: "Holy goodness I just saw @xtina and @AGreatBigWorld perform on the AMA's. So freakin beautiful! She is and sounds beautiful. Love them!"

Christina Aguilera successfully showed off her slim figure at the 2013 American Music Awards after reportedly losing 50 pounds and Life&Style revealed the singer's diet. For breakfast, Christina eats blueberries, turkey bacon and half an avocado.

The singer's snacks include celery with almond butter and shrimp cocktails. Ms Aguilera chooses chicken breast over salad and skips the creamy dressings such as ranch or blue cheese for lunch and she likes chicken or fish curry for dinner. Additionally, Christina avoids alcohol and saves up comfort food for special occasions.
