10 Co-Star Couples Who Started Hooking Up Before Their Characters Did
Kaley Cuoco and Johnny Galecki
On The Big Bang Theory it took Penny, played by Kaley Cuoco, the whole first season to realize she wanted a man like Leonard, played by Johnny Galecki. The on-screen couple would be on and off throughout the show a few times but would eventually get married during the first episode of the ninth season. In real life, the couple was already dating starting in 2007 when the series began and broke up in December of 2009. Despite the relationship not working out, Kaley and Johnny remain on good terms, which is surely one of the reasons the couple has been a staple throughout the 12 seasons. We’re sad that they couldn’t make it work in real life, but so glad that they’ve been able to weather the storm, and Sheldon, on the show.
