Sandra Bullock isn't just on top of the world — she's above it in her latest Oscar-bait, Gravity, where she costars with George Clooney. 

The 49-year-old star opens up about her three-year-old son, her three- and two-legged dogs, and her hometown love for Austin, Texas in the latest issue of Vogue, which unabashedly bills Bullock as "the biggest female movie star in the world." That's not terribly hyperbolic, given Bullock's two-decade-long career that includes an Academy Award and an ongoing stream of box office hits. 

Bullock knocks another one out of the park with her stunning Vogue cover shot, in a sequined dress with a plunging back. Take a look at the money shot below, and check out the full story and slideshow here.
