What a great choice!
Watch the 2013 MTV Movie Awards, hosted by Rebel, on April 14 at 9/8 c.
In other very exciting news, Rebel is in talks to reprise her role as Fat Amy in a Pitch Perfect sequel!
Her Pitch Perfect co-star, Skylar Astin, told MovieWeb, "I do have a meeting with a Universal representative next week. And I know that Rebel Wilson had hers last weekend. It's definitely a talking point."
Skylar explained, "I know there are so many politics in that decision-making. Also relevance. If we film this next year, and it doesn't come out for another year and a half, will that song still be popular? Will it be over played? I think they did such a perfect job. The music landed so perfectly when it came out the first time, I can't imagine, if the same people are involved, that lightening won't strike twice. I will sing whatever they want me to sing."
Are you excited for Pitch Perfect 2?
