21 Under 21: Miguelito (2011)
No. 20. Miguelito
Birthdate: Jan. 6, 1999 (age 12)
Why He's Hot: Pint-sized reggaetón star Miguelito is not only a Latin Grammy winner and regular on the Billboard charts, he's also a veritable branding machine. His line of products includes a video game ("Miguelito's Time Traveler," produced by Global Games), a line of party goods, a clothing line (Heirs), hair gel (Xtreme Gel by Miguelito), kiddie vitamins (Miguelito's Vites), a summer camp and a Christmas Miguelito Cruise on Caribbean Cruise lines. Miguelito (real name Miguel Valenzuela) debuted as a recording artist in 2006 at age 7, mentored by reggaetón star Daddy Yankee. He earned his first Latin Grammy at age 9 in 2008 for "El Heredero." The now 12-year-old star is free of baby fat and braces, sporting elegant derby hats, and readying the release of his fifth album, "Nadie Sabe lo que Tiene" in October, in tandem with the premiere of his first feature film by the same name.
