What goes on in Vegas most certainly will NOT stay in Vegas here!
Watch it go down (below)!!!
Justin Bieber, the BIGGEST selling artist on Island Def Jam over Mariah Carey, Rihanna AND Bon Jovi, was invited to sing Stevie Wonder's "Someday at Christmas" at the White House for President Barack Obama and first lady Michelle Obama.
Justin is also the first artist to have all of his songs from his debut hit the Top 100 and his first 4 singles in the Top 40 BEFORE the album's release!
Congrats to Justin and happy holidays!
