We can't get over the difference.
Christina Aguilera last night showed off her dramatic estimated 5 stone weight loss following a strict diet, at the AMAs with the difference clear in before and after photos taken just a year apart.
Christina, 32, looked virtually recognisable in comparison with the photos taken at last year's American Music Awards.
The singer hit the red carpet at the 2012 Awards in an unflattering dip-dye purple dress which accentuated her curves.

However, last night Christina chose a tight white gown with cut-away sections to flaunt the fact that her body is most definitely back.
Christina, who's mum to five-year-old Max, posed in all positions for photos on the red carpet to ensure that we all got a glimpse at her incredible new figure.
It's rumoured that Christina has lost around five stone by following a VERY strict low-carb diet.
The diet plan sees followers eating avocado and turkey bacon for breakfast, chicken with salad for lunch and chicken or fish curry for dinner. Snacks include celery with almond butter, shrimp cocktail and as a splurge, one glass of wine.
However, it's also been suggested that Christina has resorted to surgery to perfect her new body.
Hollywood Beverly Hills plastic surgeon Dr. Lance Wyatt suggested that Christina "may have had liposuction of her body and/or tummy tuck for flatter abdomen and narrower waistline."
Christina hasn't commented on the surgery rumours, but she has spoken out about how being a mum takes priority over gym sessions.
She recently confessed: "If I have to choose between working out and spending time with my son after a hard day, it’s not even a question."
