Michael Buble hosted his 5th annual Christmas television special, this year dubbed Christmas in Hollywood, this past Thursday (Dec. 10), and the legendary pop crooner teamed up with Celine Dion for a duet on one of everyone's favorite holiday classics, "Happy Christmas."
The special, which aired on NBC, featured cameos and performances from some of the film and music industry's biggest stars, from Kylie Jenner (who was shown dressed in full Mrs. Claus gear snapping a selfie with Buble during the promo) to Blake Shelton, Jay Leno, famed supermodel Gigi Hadid and many more.
After the promo was played on live television, the 40-year-old singer entered the stage with all of the women in the audience visibly love-struck, making a few comical quips, including mentioning that if Donald Trump is elected, his wife and family wouldn't be allowed into the country (considering she is Argentinian). Shortly thereafter, Tori Kelly performed "This Christmas" backed by a full orchestra, followed by a duet with Buble himself on "Jingle Bells."
The highlight of the evening, however, was certainly Buble and his friend Celine's duet, with each seasoned pop icon singing each and every line perfectly, molding together in perfect harmony. If that wasn't enough for you, Dion will continue her residency at Ceasars Palace in Las Vegas through 2016, all dates of which can be found via her official website.
The Christmas special was not Buble's first Christmas endeavor this year. The singer previously performed at Radio City Music Hall and was joined by Ariana Grande on a duet. Speaking on this year's Christmas special, however, the singer spoke to PEOPLE about his joy in making it all happen. "I put everything I have into this special," he said. "I put a lot of heart and soul into it, and hard work and money, and I ask a lot of favors. So there's a great sense of pride once this is done."
