After releasing an original holiday song, "Mistletoe," last Monday (Oct. 17), Justin Bieber kicks off this week by unveiling a cover of a Christmas classic -- with a little help from his mentor, Usher. "The Christmas Song (Chestnuts Roasting on an Open Fire)," which will be included on the Biebs' forthcoming Christmas album "Under The Mistletoe," premiered on Ryan Seacrest's syndicated radio show on Monday.
Over a twinkling piano and finger snaps, Bieber lets his R&B vocal stylings shine before Usher joins in with a triumphant, "They know that Santa's on his way!" An unexpected electric guitar solo arrives at the 2:07 mark before the male pop stars trade words on the final chorus.
"This record is going to be remembered for years to come," Usher told Seacrest on his radio show this morning. "It's a record that has always been on of my favorites, and I'm happy that I was able to share it with Justin, and for us to put it out."
Bieber and Usher had previously teamed up for "Somebody To Love," off the teen superstar's "My World 2.0." "Under The Mistletoe," due out Nov. 1, also features guest appearances by Boyz II Men, Mariah Carey and the Band Perry, among others.
The video for "Mistletoe" was released last Tuesday, and the clip -- an old-fashioned Christmas love story -- has already racked up 17 million views on YouTube. Bieber was also confirmed to perform at the 2011 American Music Awards on Monday.
