Here comes the bride (with an asterisk!). Kaley Cuoco looked all sorts of beautiful as she walked down the aisle on Monday ... but it was all just for show.

The actress married Johnny Galecki on the season 10 premiere of "The Big Bang Theory." After the episode aired, she shared a behind-the-scenes image of TV couple Penny and Leonard on their magic TV day, posting a Polaroid pic of the duo to her Instagram.

The dress is a sight to behold. In her role as Penny, Kaley wore a knee-length dress that featured intricate lace details and a high sheer neckline. She also wore a pink and white floral crown in her hair. Johnny, in his role as Leonard, looked sharp in his taupe suit.

On the show, it was actually the second time the duo has married... technically.

"Leonard, standing here in front of all our family and friends is bringing up a lot of feelings — like what a good idea it was to elope the first time," Penny said. "But also how incredibly happy you make me. Thank you for marrying me — hopefully for the last time."

Leonard responded, "Penny, as a scientist, my job is to figure out why things happen. But I don't think I'll ever understand how someone like me could get to be with someone like you. Maybe I don't need to understand it, I just need to be grateful. I love you, Penny!"

A week ahead of the TV nuptials, Kaley shared an image from her character's wedding day, erasing any thought that she would say "I Don't (as if that was ever going to happen!).

"We finally meet Penny's mom and bro on tomorrow's epic season premier of @bigbangtheory_cbs ! Don't miss it! #allstarlineup #amidreaming (oh and we get married. Again.)," she captioned a photo, shared last week on her Instagram.

Last week, the show's official Instagram account also shared an image from the wedding day.

It's a family affair as The #BigBangTheory's Leonard and Penny tie the knot...again!
