It was just months ago when Darci Lynne Farmer captured America's hearts by winning America's Got Talent with her unparalleled ventriloquist skills. With the help of her 'friend' Petunia, the 13-year-old Oklahoma City native has been stunning audiences non-stop since she first set foot on the national stage.

Not only is Darci an incredible talent who can make ventriloquism look easy through conversation, but she is a terrific singer through her acts as well — which is why Pentatonix invited Darci and Petunia to join their Christmas special this year.

The pair come on stage, Darci admitting she's a big fan of the A capella group, Petunia admitting she’s never heard of them.

After some laughs Darci puts on a show, allowing Petunia to sing seemingly the only Christmas song she knows, "O' Easter Egg." Although Petunia is 'singing,' Darci's mouth doesn't budge.

It's a short, sweet segment that aired during "A Very Pentatonix Christmas." But it's also a reminder that Darci has a very long, bright future ahead of her as an entertainer.
