Johnny Galecki is allegedly to blame for Kaley Cuoco and Karl Cook’s split.

In its September 27 issue, National Enquirer claimed that Cuoco immediately turned to her ex-boyfriend and former Big Bang Theory co-star, Galecki the minute she and Cook started having problems.

A source claimed that Cuoco has always felt that there’s an unfinished business between her and Galecki.

“She and Johnny never got the chance to have a proper relationship because they had to hide it from the world while working on the show,” the source said.

And now that Galecki is also single, the source claimed that he and Cuoco could finally get back together.

“Now, Jonny and Kaley are both free to get back together and renew their love,” the source said.

Just days ago, Cuoco and Cook announced their decision to go their separate ways.

In their joint statement, the exes said that they still love and care about each other. The actress also stressed that there’s no animosity between them.

Immediately after, multiple tabloids accused Pete Davidson of being the reason behind the split. After all, Cuoco and Davidson are filming a movie together.

Shortly after the divorce announcement, Cuoco posted loved-up photos of herself with Davidson while strolling the streets of New York.

Fans immediately accused the two of secretly dating after spending a lot of time with each other on set.

However, Cuoco has not revealed that real reason behind her split from Cook. And it seems she never will. But her silence doesn’t automatically mean that she cheated on her ex-husband.

For now, Cuoco and Davidson are nothing more than friends and co-stars. And as for Cuoco and Galecki, they are also exes that have managed to stay friends.

Cuoco and Galecki didn’t also have to hide their relationship while they were on Big Bang Theory. In fact, the entire world knew that they were dating back then.

Even though their relationship was short-lived, Galecki and Cuoco continued to play the roles of a couple in the hit CBS sitcom.

In Big Bang Theory, Galecki played the role of Leonard while Cuoco played the role of Penny. The two ended up together, and they also tied the knot in front of their good friends, Sheldon (Jim Parsons), Amy (Mayim Bialik), Howard (Simon Helberg), Melissa (Bernadette), and more.
