Off screen, this triple threat is just as winning as his Ugly Betty alter ago. An aspiring performer since birth, Indelicato made his acting debut at age 8 in La Vie en Bleu at Philadelphia's Walnut Street Theatre. He then showed off his singing skills in concert with Clay Aiken, at a New York Knicks' halftime show and on his children's album Little Maestros. He only had two TV guest spots under his belt before landing his breakout Ugly Betty role as the title character's fashion-loving, show-tune-singing, preteen nephew. Indelicato instantly won the hearts of viewers and — although the character's sexuality wasn't addressed directly on the show — sparked an interesting public discussion about sexual orientation in adolescents. In his spare time, Indelicato enjoys playing video games, especially Mario Kart.
