Justin Bieber seems to have caught the Christmas spirit of giving this year as he gave his best friend Ryan Butler a convertible Mustang on Sunday.

Justin got me a present. #swag, Butler tweeted along with a picture of his brand-new two-door ivory convertible Mustang.

The much-anticipated performance will take place in front of 1 million people just before the ball drops on Dec.31st. It will be the 40th anniversary of the city's celebrations and broadcast live on ABC.

It hardly seems possible that we began telecasting, New Year's Rockin? Eve? 40 years ago. Armed with just a couple of cameras and a skeleton crew, my wife and I stood atop a Times Square building and watched the thousands of happy celebrants in Times Square, Dick Clark said in a statement. The army of talent we had join us over the years has truly been outstanding, and this year we top it off with an appearance by Justin Bieber and Lady Gaga.
