Diego is all grown up.

Five years ago, Diego Andrés González Bonetta was a cute 13-year-old in the finals of Codigo F.A.M.A. – think "La Academia," for kids. Diego didn't win, but he eventually became a tween heartthrob in México by parlaying his appearance on "Codigo" into acting roles on youth telenovelas like Alegrijes y Rebujos and Misión SOS: Aventura y Amor.

At 14, Diego took on the role of Roco in REBELDE, the inspiration for RBD. With his wavy locks and dimpled chin, he soon won the hearts of teens from Tijuana to Tuxtla Gutiérrez. RBD's Dulce Maria had nothing but praise for her young co-star: "[Diego] may be one of the youngest ones here, but I swear he's also one of the most mature."

In 2006, Diego returned to music, releasing a self-titled album of grown-up pop that belied his 16 years of age. He scored a hit with Solo Existes Tú, a catchy pop-rock track with playful synths and a pulsing bass guitar. He embarked on an international tour that took him to Brazil, Chile, Romania, Spain and the U.S.

Earlier this year, Diego dropped Perdido En Ti, a rock anthem which he also recorded in English (Losing Me), from his forthcoming Jonas Brothers-meets-Alex Ubago album, Indigo. Featuring production by Guy Chambers (Robbie Williams) and Matt Wallace (Maroon 5) and co-signed by the legendary Juan Gabriel, Indigo is scheduled for release next month. Diego says building the courage to collaborate with such big names isn't scary: "What scares me more, is not trying anything at all."
