WATCH: Kaley Cuoco & William Shatner in New Priceline Commercial

William Shatner is getting a new commercial co-star!  Shatner has starred for years as the “Negotiator” for Priceline, but now the travel services company wants appeal to a younger audience.

They’ve tapped The Big Bang Theory actress Kaley Cuoco to play Shatner’s secret daughter in an ad campaign set to air January 14.

In the commercial, 27-year-old Cuoco plays a chip-off-the-old-block to 81-year-old Shatner, who has trained her well in the art of finding the best travel deals.

Cuoco says the two had “way too much fun” during filming, and Shatner called her “quite a talent.”

The actors will shoot two more commercials to be aired this summer.

Cuoco reveals there is an inside joke to her character’s Priceline role, but only Star Trek fans and viewers of The Big Bang Theory will make the connection!

“The nerdy factor, the Trekkie stuff, it goes with ‘Big Bang’ and it all worked together,” she says.
