14. Miguelito: 21 Under 21 (2013)


Last Year's Rank: N/A

Birthdate: Jan. 6, 1999 (age 14)
Why He's Hot: At 14 years old, Puerto Rican singer Miguelito already boasts a Latin Grammy and a multi-million dollar branding business that includes "Miguelito" vitamins, clothing line, videogame, summer camp, party goods and a themed cruise. According to manager dad Wascar Valenzuela, Miguelito-branded products have sold over $70 million to date. That's because Miguelito is the rare child star in the Latin music realm. But he's fast growing up. With a newly minted representation deal with CAA and a new record deal with BlastMusic, Miguelito is poised to crossover early next year with new album, "Here To Stay." "People tell me I'm a 21 or 30-year-old mind inside a 14-year-old body," says the erstwhile reggaetón star.
