Kaley Cuoco and Karl Cook – Together For 4 Years
Big Bang theory fans almost got what they wished for when Kaley Cuoco and her co-star and on-screen love interest Johnny Galecki started dating during the early days of the show. But that relationship didn’t work out, and neither did her marriage to professional tennis player Ryan Sweeting.

But it seems like the third time’s the charm. Cuoco started dating equestrian Karl Cook, son of billionaire director of eBay Scott Cook, in 2016. The relationship moved quickly with the couple getting engaged in 2017, and were married by 2018. Cuoco is set to star in the web series The Flight Attendant and in the 2021 feature film The Man From Toronto
