Two classy singers of this generation have appeared in a music video duet together for the holiday season.

Broadway star Idina Menzel who's also known for random film and voice roles (including Elsa in Frozen) sings "Baby, It's Cold Outside" featuring jazz singer Michael Buble. The two lend their voices in a charming video released on Monday where they only briefly appear since the duet stars two kids.

A boy and a girl are dressed in elegant old-fashioned attire as they step off an elevator and the boy realizes that he needs to woo the young lady. He rushes out of his bellhop outfit into a tuxedo and takes the girl's hand.

Is There Going To Be A Sequel To 'Frozen?'

The two let their chemistry fly as they dance and lip-sync to Buble and Menzel's wide vocal ranges. Even though they're just kids, they express some gratitude and happiness to be around each other.

Some other random children show up as they give some facial expressions that flaunt star quality. Menzel and Buble even have little cameos as the kids' reflections where they give these youngsters a boost of confidence.

The song is even more child appropriate considering that a couple lyrics have been changed. "Maybe just a cigarette more" is now "maybe just a soda pop more." This leads into the young man taking a napkin and wiping the girl's nose clean when she gets whipped cream on it.

Check out the video below and see what else these young performers can do with their talent.
