Q What can you tell me about Camille Guaty on Las Vegas? She looks familiar, but I can't place her.
—T. Thomas, Ketchum, Idaho
California-born Guaty, 29, who plays feisty casino concierge Piper Nielsen on the NBC-TV series Las Vegas, got her start as a contestant on the WB network's singing competition Popstars: USA. She didn't win, but the show opened the door for her first acting role in the 2000 movie Chaos Theory. She also appeared in the 2002 Disney Channel movie Gotta Kick It Up! before landing her first series role in the WB's Raising Dad, followed by Crossing Jordan, Prison Break and The Nine.
