What a difference a year makes!

Christina Aguilera has been hitting the gym hard – and boy does it show! The singer, 32, appeared on the red carpet at last night’s American Music Awards looking a shadow of her former self.

Wearing a skin tight white dress, split to the thigh, Xtina oozed confidence, and was keen to show off the results of her hard work, which includes a very low carb diet.  The mum of one was pictured at the same event in 2012 looking noticeably heavier. It’s estimated that she’s shed at least five stone in 12 months.

However, despite her incredible new figure, it’s good to know Christina has her priorities right.

‘If I have to choose between working out and spending time with my five year old son after a hard day, it’s not even a question,’ she recently confessed.

Good to hear it!
