Kaley Cuoco and Johnny Galecki

If you have been co-stars for 12 whole seasons on one of the most in-demand television sitcoms of all time, you are bound to get together with your fellow on-set star. Kaley Cuoco and Johnny Galecki are two of the main characters in The Big Bang Theory. It is safe to say that they are friendly exes because they have been able to maintain their friendship even after splitting up.

They started dating in secret back in 2007. These former lovers never brought their romantic relationship on the set of their famous sitcom. Cuoco and Galecki were so careful about it that they never went anywhere together. Eventually, it took a toll on them, and they ended up going their separate ways in 2009. They may have broken up, but the degree of love this duo had for each other was so strong that they have no hard feelings for each other. In fact, Galecki happily attended Cuoco’s wedding in 2018. Cuoco also admitted that she couldn’t wait to meet her best friend’s son, Avery.
