Lookin' good lady! Christina Aguilera showed off the results of her 50-pound weight loss when she showed up in a Two Broke Girls sketch during the People's Choice Awards on Wednesday.

Teaming up with the ceremony's hosts, Two Broke Girls stars Kat Dennings and Beth Behrs, the 33-year-old songstress showed off her sexy legs, and small waist and décolletage when she stepped out in a glittering versions of the waitress uniforms that they wear on the show.

The petite dynamo paired the skimpy frock with red platform heels as she pretended to call out orders in the show's intro sketch.

At one point the girls warned that they don't get a lot of tips in their thankless job, and the ample-bosomed Xtina then proceeded to point to her chest and say, "Don't worry ladies, I get a lot of tips." Hey oh! Get it guys -- it's 'cause Christina Aguilera has big boobs?!

The star-studded show also feature appearances by Drew Barrymore, Ellen DeGeneres, Justin Timberlake, Britney Spears, Jessica Alba, Christina Aguilera, Emily Deschanel, Zac Efron, Sarah Michelle Gellar, Melissa McCarthy and more.
