Golden Globes: Kaley Cuoco opens up about filming emotional 'Big Bang Theory' finale

Grab your tissues for "The Big Bang Theory" finale.

Kaley Cuoco, 33, opened up about filming the last episode of the CBS sitcom while on the Golden Globes red carpet Sunday and like the rest of us, she expects a lot of tears.

"Going into Season 12, we were like, 'We've got a whole season and a lot of episodes,'" Cuoco said during an interview with E! News' Ryan Seacrest. "Now we're on the second half and it's starting to get a little heavy."

She continued: "There's some tears welling up. I hope we preshoot the whole last episode, because I don't think I'll be able to keep a dry eye."

Cuoco, who plays Penny in "Big Bang Theory," admitted that despite the top-rated comedy's continued success, the cast and crew still wonder if fan's will love each episode.

"I have to be honest, even after all these years, we still come in after a new episode and we're like, 'Did people watch?' We still are shocked that people are so intrigued."

"The Big Bang Theory" will end its run in May, but Cuoco didn't rule out the idea of reviving the show at some point.

She told Entertainment Tonight on the carpet: "Everyone’s doing rebooting. We might as well do it in, like, a year! I'm fine with that!"

She added that the cast is OK with the show finally wrapping.

"Everyone is still madly in love with each other. We're all OK with the choice," Cuoco said. "We’ve just grown up together, so it’s our adult decision."
