There's no question that Reese Witherspoon has had a wide-ranging and accomplished movie career, and at Sunday's 2011 MTV Movie Awards, the Oscar- and Golden Globe-winning actress will add one more award to her already-crowded mantle. Witherspoon will receive this year's Generation Award, previously bestowed upon superstars like Adam Sandler and last year's recipient Sandra Bullock.

"Reese Witherspoon is one of the most versatile and accomplished performers of her time," MTV President Stephen Friedman said in a statement. "Our viewers admire her for taking risks and for the breathtaking range of her roles. She fearlessly moves between dramas and comedies and always leaves everyone guessing what she'll do next. We are thrilled to honor Reese with this year's 'MTV Generation Award.' "

With a résumé already filled with comedies like "Legally Blonde" and "Election" and more serious roles in films like "Walk the Line," "Cruel Intentions," "Pleasantville" and "Water for Elephants," the actress has proven that there's no role she can't handle. Her Southern charm and girl-next-door looks have enchanted audiences during her two-decades-long career, going from child star to full-fledged A-lister. She's starred alongside everyone from Robert Pattinson, Joaquin Phoenix, Ryan Phillippe, Jake Gyllenhaal, Owen Wilson and Luke Wilson, as well as Tobey Maguire and Vince Vaughn, to name just a few.

This certainly isn't Witherspoon's first Golden Popcorn. She previously won Best Comedic Performance in 2002 for "Legally Blonde" and was nominated for Best Female Performance, Best Dressed and Best Line for her star-making turn as Elle Woods. In 2003, she was nominated for Best Female Performance for "Sweet Home Alabama" and was up for Best Performance for "Walk the Line" back in 2006.
