AMERICAN IDOL's Diana DeGarmo On THE YOUNG AND THE RESTLESS Debut: "Not to be missed"

On Monday, October 31st, Season 3 AMERICAN IDOL runner-up Diana DeGarmo will make her debut on THE YOUNG AND THE RESTLESS as Angelina, the Jersey-girl daughter of mob boss Angelo (Mike Starr).

DeGarmo landed the role as Angelina by performing at the right place at the right time.

“I booked the part thanks to a performance of 'Hairspray' I was in at the Hollywood Bowl in early August," she explains in a new interview with AmericanIdol.com. "The right people from Y&R were in the audience and were pleased with my performance, and apparently they saw me as a perfect fit for the gum-smacking Jersey girl who can’t sing.”
