Kaley Cuoco revealed that she dated Johnny Galecki from 2007 to 2009. She also revealed that the affair was kept a secret from almost all members of the cast.

Cuoco also revealed that it bothered her to keep everything under the covers. She said that although the relationship was beautiful because they could not speak about it or go anywhere together, it wasn’t fun. She said that it took a toll on her to deny the fact that she loved him.

She also added that they did that because they didn’t want their relationship to affect their professional relationship. Both the actors had agreed not to let their personal matters affect work.

In an interview, Galecki also revealed that he considered Kaley more than an ex, that she is a part of his life. It is remarkable how the duo kept everything under wraps and didn’t let it affect anything on the show.
