Rihanna Keeps It Short And Sweet For Late Night Bite

For Rihanna ... the thighs the limit when it comes to rockin' short shorts!

The sexy songstress left her favorite Santa Monica spot, Giorgio Baldi, showing off a whole lotta leg and a gold grill. Too bad she didn't give us a big smile so we could catch a better glimpse of her golden chompers.

RiRi rocked the stage over the weekend at the MTV VMA Awards, and after dinner last night, she was in the recording studio until 4am. Even though it was a long night, the gorgeous singer left looking fab.

Thanks for the smirk, baby doll!
