The Nancy Drew actress shot to fame playing a singing teenager in U.S. TV series Unfabulous, and she released her debut album, the show's soundtrack, in 2005.
The 20 year old insists she is more focused on acting at the moment, but hopes to one day emulate Witherspoon's turn as June Carter in Johnny Cash biopic Walk the Line and Paltrow's singing spot in last year's (10) Country Strong.
She tells JustJared.com, "I just think you can't ever be seen as both equally. You are always going to be one more or the other. For me, I want to be an actor.
"I would love to do something like Country Strong or Walk the Line where they sang in a movie. I think that would be really interesting.
"As far as an album, I just think it's too much. I can't be in front of people that often, I need time to myself and I barely have time to myself, let alone if I was on tour or being a singer."
