Marc Anthony Duets with Tony Bennett

By

This Sunday, Tony Bennett stars in Univision's holiday special Feliz Navidad con los Nuestros ... Tony Bennett y Sus Amigos with a myriad of Latin music artists, including a star struck Marc Anthony.

In our advance clip of the show above, Anthony is seen crooning with the show business legend and gushing over the experience in Spanish, but he wasn't the only one grateful for the opportunity. Bennett was appreciative as well.

"It has been a heartwarming journey to meet and record with all the artists from the Latin music world and I have been overwhelmed by their generous spirit and musicality," said Bennett. "I am truly honored to have been welcomed into this community of artists."
