Bieber and Smith gift fans with New Year track

Singing sensation Justin Bieber teamed up with Will Smith's son Jaden to treat fans to an extra-special gift on New Year's Day (01Jan12) - a previously unreleased song.

The Baby hitmaker took to his Twitter.com page on the first day of 2012 to share the New Year-themed track, which features rap verses from his pal Smith.

Bieber tweeted, "Thank you for 2011, let's have a better 2012! Happy New Year."

In the festive track, the pop star sings, "2012 is a year to be better, stronger and closer to the people around you. So grab someone special and just, you know, 5-4-3-2-1, kiss me."
