The 32-year-old singer showed off her 30-pound weight loss at an NBC press event for The Voice this weekend and she absolutely rocked the red carpet in her hot pink mini-dress!
The Voice judge took last season off (with Colombian superstar Shakira standing in for her) to focus on her son AND herself...and it looks like she put in some serious sweat sessions during her "break."
Christina also reportedly used a meal delivery service called FreshDiet, where she had calorie-controlled meals delivered directly to her.
While we always think Christina looks gorgeous, she is definitely looking better than ever these days and we can't wait to see her back on The Voice judges' panel next season!
Christina isn't the only slimmed-down superstar. Take a look at these other amazing celebrity slim downs!
