Is there anything Sandra Bullock can't do? The single mother and Oscar winner (already a frontrunner for a second Academy Award for Gravity) added another line to her impressive resume -- rapper -- when she visited Britain's The Jonathan Ross Show on Saturday, Oct. 12.

The 49-year-old actress -- who looked stunning in black shorts, a black-and-white jacket, and black heels -- was on the show to promote her acclaimed new movie, Gravity, also starring George Clooney. But the highlight of her appearance was an impromptu performance of the 1979 hip hop classic "Rapper's Delight," by the Sugarhill Gang.

"The sad part is, I learned the words because I liked this guy in high school," Arlington, Va., native Bullock recalled of the song. "And I was like, 'Next time I go to that dance, I'm gonna know every word. And I'm going to make sure he sees me lip-syncing it, and I'm gonna catch his eye, and I'm gonna say the words. And he's gonna like me."

So, did he? "Sadly, it worked," she quipped, laughing.

Host Jonathan Ross then asked if she'd do a little demonstration. Bullock agreed -- on one condition. "I need some beats," she joked. "Gimme some beats, yo."
