Miranda Lambert Presented With Female Vocalist of the Year Award by Robert Pattinson and Reese Witherspoon at 2011 ACMs

'Water for Elephants' movie stars Reese Witherspoon and Robert Pattinson passed out the statue for Female Vocalist of the Year at tonight's ACMs, and the award went right into the hands of Miranda Lambert -- soon-to-be Miranda Shelton.

A teary-eyed Lambert -- who also pocketed Video of the Year, Song of the Year, and Single Record of the Year awards -- used the opportunity to thank her dedicated fans. "I don't know why I'm up here," the 'White Liar' singer admitted. "I feel so blessed and so humbled, and I really thank everybody."

She continued, "I love country music fans. Thanks for coming out to the shows and thanks for believing in me, I love y'all so much."

Lambert was rightfully amazed at her accomplishment -- the Texas native sat among music's greatest for the Female Vocalist of the Year Award, including Reba McEntire, Taylor Swift, Carrie Underwood, and Lee Ann Womack.
