Chris Harrison's Dream 'Bachelorette': 'Big Bang Theory' Star (Recently Single) Kaley Cuoco

Are two worlds about to collide in one big bang? Bachelor host Chris Harrison has revealed his dream casting for the show's coming season of the Bachelorette and it includes Big Bang Theory star Kaley Cuoco.

There might have been 8 Simple Rules for dating her back in the day, but could the recently single star be laying down the rules for 25 eligible bachelors on a season of the ABC matchmaking show?

According to Glamour, Harrison feels that the A-list actress would be perfect for season 12, for which there's not yet a leading lady.

"Kaley would be great," the 44-year-old longtime host said of his pal. "I would love that. She's an old friend of mine from the ABC days, and I think she likes to drink wine as much as I do."

However, Harrison does say getting the Big Bang star on the show might be a little difficult, given her busy schedule and her celebrity.

"It's hard to find a good single celebrity," Harrison said, according to People. 

And Cuoco may be off the market. She has often been linked to her co-star and former boyfriend Johnny Galecki. Most recently she's been linked to Arrow star Paul Blackthorne.

However, fans of the show shouldn't get discouraged yet -- the series has bet on other celebrities, according to Us Weekly: New York Giants quarterback Jesse Palmer was the star of The Bachelor's fifth season, and actor Charlie O'Connell handed out the roses during Bachelor season seven.
