The Big Bang Theory spoilers: Penny and Leonard's wedding is a 'distant planet' away, says Kaley Cuoco Sweeting

The Big Bang Theory star Kaley Cuoco-Sweeting opened up about Penny's wedding in the hit CBS series.

Cuoco-Sweeting said that the big wedding between her character Penny and Leonard (Johnny Galecki) is still a long way to go.

"Penny and Leonard took so long to get engaged that a wedding to me sounds like in a distant planet," Cuoco told Zap2it.

"I don't know what the writers have planned. I know they've said that they've thought about it and they're going to do something very unique and special, which I don't even know about, that'll just be completely different from what anyone expects."

She continued, "But that's kind of Big Bang for you. You never know what you're going to get."

Cuoco-Sweeting also recently won the Favorite Comedic TV Actress award at the People's Choice Awards, beating New Girl's Zooey Deschanel, Mike & Molly's Melissa McCarthy, Parks and Recreation's Amy Poehler and Modern Family's Sofia Vergara.

In her speech, she said she loved playing Penny and is hoping to play her for years to come.

The Big Bang Theory airs Thursdays at 8 pm on CBS.
