If you're interested in seeing more of the actress who plays the daughter of William Shatner's Negotiator character in the Priceline ads, you can catch her in her little side-gig as the female lead in one of the biggest shows on television.

Shatner's co-star in the spots is Kaley Cuoco-Sweeting, who plays Penny on the long-running sitcom hit "The Big Bang Theory."

With such a high-profile role, you wouldn't think the star would bother doing TV commercials. But she pointed out that working with Shatner is a good fit with her day job.

"The nerdy factor, the Trekkie stuff, it goes with 'Big Bang,' and it all worked together," she told the Associated Press back in 2013, when she first started appearing in the ads.

Of course, Shatner's Negotiator character dates to well before then. She told AP that Shatner had made Priceline "cool," but not necessarily with the young crowd to which she appeals. (Though "The Big Bang Theory" is a hit with audiences of all ages, Cuoco-Sweeting is still particularly popular with the young -- she was nominated for yet another Teen Choice Award this year, her seventh such nod.)

And though she's only gotten more successful since the first ads shot in 2013, she hasn't given them up. A new installment was filmed earlier this year.

It's not as if she needs the money, either. She signed a contract last year that nets her $1 million per episode of "The Big Bang Theory," which is still going strong on CBS.

If sitcoms about socially hopeless nerds aren't your thing, she's leveraged her TV fame into a big-screen career as well. She starred in this year's hit comedy "The Wedding Ringer," last year's "Authors Anonymous" and did a voice in the animated hit "Hop" in 2011, among other roles.
