Best known as Hazel Williams in 'Gossip Girl,' Dreama Walker's career is taking off lately.

With guest spots on 'The Good Wife,' ,'Law & Order: Criminal Intent' and 'Mercy,' she's certainly primed to make those next level career steps young actresses need.

In doing so, she stars in her first leading role as Harper Grace in 'Seven Deadly Sins' (Sun., May 23, 8PM ET). The TV movie takes the notion of the "seven deadly sins" and weaves them in a modern high school setting-the film has the look and feel of modern day teen dramedies such as 'Gossip Girl' and 'The O.C.,' with fast dialogue, a group of kids who might think they're a little too grown up than they really are. And as you might suspect, some trouble goes down.

TV Squad spoke to Walker from her home in Manhattan about high school backstabbing, her own recent exploits with the seven sins and her future projects.
