She'll be the voice of Sofia, a young princess in the making, according to Disney. Sofia will have her own TV series and movie on Disney Junior starting in 2012.
The tale of Sofia the First starts when Sofia’s mom marries a king and she's plopped into a luxurious life (featuring exciting cameos of other Disney princesses).
The movie will be released on the Disney Channel in fall of 2012 and the television series will follow in 2013. Grey’s Anatomy’s Sara Ramirez, Wayne Brady, and Project Runway’s Tim Gunn will join Ariel as the voices of the royal kingdom and family.
Unlike other Disney princesses, who are adults, Sofia is a young girl. Disney Junior hopes she'll be a hit with kids ages 2-7.
