Christina Aguilera makes her triumphant return to The Voice this September for Season 5 and we can't wait to see her sexy new look! The 32-year-old diva was spotted out and about shopping in Beverly Hills on Thursday (August 8) looking slim and trim in a grey top and skinny jeans.  

See the pictures of Christina here.

A few weeks earlier at the 2013 TCAs on July 27, Christina stunned fans and reporters when she stepped out looking super slender in a little pink dress. She's practically half her size from the year before!

According to sources close to the pop star, she dropped a total of 20 pounds using a home delivery plan called The Fresh Diet (for the cool price of $1,394.69 a month). Christina also reportedly started weight training with fitness guru Tee Sorge and practicing yoga.

We think Xtina looks fabulous at any weight, but she certainly seems more confident these days and that's what matters most.

"As long as I'm happy in my own skin, that's all I need," the pop singer said in January 2012.

All we need is more Christina in our lives. To catch the "Beautiful" singer in action, don't miss the Season 5 premiere on The Voice on Monday, September 23 at 8 p.m. ET on NBC. Will you watch?
