Sandra Bullock School Golden Globe Oscar Nominee

Sandra Bullock School Golden Globe Oscar Nominee

It's official: Sandra Bullock is the most jovial leading lady in Hollywood.

The Gravity star was smiling from ear to ear while running errands on Friday in Los Angeles. Whether elated to be spending quality time with her adorable son Louis or still thrilled about her Oscar nomination, Sandy was overjoyed, nonetheless -- a far cry from her Gravity character.

Despite early buzz about her performance (arguably a career best) in the space drama, Sandra has been left relatively empty handed this awards season thanks to Cate Blanchett. Although the Blue Jasmine star nabbed best actress at the Critics' Choice Awards last week, Sandra still grabbed a statue for best actress in an action movie -- her biggest win this season.

That will hopefully change come March 2 when Sandra faces off against Cate, Judi Dench, Meryl Streep and Amy Adams for the gold. Sandra's near one-woman show, which she described as the most physically, mentally and emotionally challenging role of her lifetime, was perfection.
