Watch: Mariah Carey's Pooch Makes Music Video Debut
It's Jill E. Beans's big moment!
One of Mariah Carey's beloved jack Russell terriers makes her music video debut in the Justin Bieber duet, "All I Want for Christmas Is You", which premiered during NBC's Rockefeller Center tree lighting ceremony Tuesday night.
Carey is seen cuddling the adorable pooch at the 4-minute mark – and Bieber can't resist giving the little cutie a rub!
Filmed at Macy's in New York City last month, the video took a full night to shoot, and both stars got in some early Christmas shopping while they were there.
We hope Jill E. Beans crossed a few names off her list, too.
