An Oscar. A Golden Globe. Almost $700 million in worldwide box-office sales. From "The Blind Side" to "The Proposal," Sandra Bullock has had one heck of an amazing year on the big screen — a richly deserved payoff after a more than two-decade-long career in Hollywood. That's why at the 2010 MTV Movie Awards, we're bestowing MTV's highest honor, the Generation Award, to Bullock, who will be on hand during the show to accept the honor.

And, of course, we just kinda love her. How can you not? She's played sweethearts and badasses, damaged and righteous women, goofy gals and damsels in distress. She's shared the screen with Sylvester Stallone, Keanu Reeves, Matthew McConaughey, Nicole Kidman, Ben Affleck and Ryan Reynolds. She can pop off LOL-inducing one-liners in one movie and execute a sucker-punch to your soul in another. She's already won four MTV Movie Awards.

For all these reasons and more, Bullock is this year's MTV Generation Award honoree. Past recipients include Ben Stiller, Adam Sandler, Mike Myers, Tom Cruise and Jim Carrey, but this is the first time a woman has ever been honored.

"Sandra is one of those rare individuals who is adored by our audience as both an actress and a role model," said Stephen Friedman, general manager of MTV. "Recognizing her remarkable talent, amazing range of films and her visceral connection to our audience around the globe, we are honored to present her with our MTV Generation Award."

It's set to be a big evening for Bullock, as both "Blind Side" and "Proposal" are up for awards. Fan voting in all of these categories is now under way at MovieAwards.MTV.com and will stay open through Saturday, June 5. Voting for Best Movie, however, will stay open throughout the awards show itself, which means you'll have a chance to affect the night's biggest prize until the very last minute.

Hosted by Aziz Ansari, the Movie Awards air live Sunday, June 6, at 9 p.m. ET. "The Hangover" leads the field with six nominations, followed by five each for "Avatar" and "New Moon." Robert Pattinson, Kristen Stewart and Taylor Lautner will be in the house to present an exclusive clip from "Eclipse." Christina Aguilera is set to perform a song from new album, Bionic, while Katy Perry will take the stage for a rendition of her summer anthem "California Gurls." Confirmed presenters include Tom Cruise, Cameron Diaz, Zac Efron, Jonah Hill, Jessica Biel, Bradley Cooper, Steve Carell, Miranda Cosgrove, Shaun White, Vanessa Hudgens, Sean "Diddy" Combs, the cast of "The Grown Ups" (Adam Sandler, Kevin James, Chris Rock, David Spade and Rob Schneider), Paul Rudd, Jason Segel, Anna Kendrick, Christopher Mintz-Plasse and Aubrey Plaza.
