NIKKI BLONSKI was an unknown actor before she landed the role of Tracy Turnblad in the 2007 Hairspray remake. The role launched her to stardom, however it seems like she is now being typecast in roles that have her dealing with her self image. I'm not sure if that is her choice, but I've noticed the pattern with the TV movie Queen Sized and the short-lived TV series Huge.
Although Blonski isn't labeled a Disney Channel star, she appears on DISNEYMANIA 6 singing A Dream is a Wish Your Heart Makes. Nikki has a beautiful voice and this particular arrangement of the Cinderella classic is surprisingly good and not at the same level of cheese as a typical DISNEYMAINA cover.
