Justin Bieber scored the top spot in Billboard's annual "21 Under 21" list -- with One Direction hot on his tail. All members of the band or group have to be under 21 and Justin scooped up the number one spot with his success of Believe and his sold out nationwide tour.

• Billboard said, "Since earning last year's crown, Bieber has snagged two more Number 1 albums - the holiday set Under the Mistletoe and the more adult-leaning, full-length Believe. He converted more Beliebers with slick award-show performances, radio hits like 'Boyfriend' and 'As Long As You Love Me,' tabloid-ready pictures with girlfriend Selena Gomez and those adorable, now-legal good looks."
