Britney Spears

Britney Spears is on a roll!

At least when it comes to flaunting her fit figure. After making jaws drop last week by wearing a white hot bikini on the cover of Shape magazine, it looks like, oops, she did it again!

While hitting up KIIS FM's Wango Tango concert in Carson, Calif., on Saturday the singer looked svelte in a one-shoulder Roberto Cavalli frock with gold Saint Laurent pumps. The LBD's sheer pannels even allowed her blingy belly ring (the same one that appears front and center on Shape's cover) to shine though.

Equally as flawless were the mother of two's bombshell waves and smoky eyeliner.

Britney must have been enjoying her Mother's Day weekend, as she seemed completely comfortable posing on the red carpet, even sharing a few laughs. Perhaps her new beau David Lucado is at least partially responsible for her clear confidence boost.

What do you think of Britney's LBD look?
