She added in the caption that they’re just friends and playing the roles of Penny and Leonard will suffice. The co-stars dated for two years and Cuoco admitted this back in 2010, according to ET Online.

Galecki also posted a black and white photo with the actress and captioned it “No scandals / home wreckers / pregnancies here, y’all. Just profound friendship.”

They are also not getting back together despite Cuoco’s recent divorce.

According to New York Daily News, there are rumors that Galecki is the reason why the actress filed for divorce because she still has feelings for him.

The 29-year-old actress called it quits with husband of 21 months Ryan Sweeting citing irreconcilable differences. What started as a whirlwind romance also ended just as fast.

There were already rumors that the couple was having problems but Cuoco was quick to deny it posting in social media back in April that she’s never been prouder of her husband who was recovering from injuries at that time.

Sources told ET that the split was a long time coming. Cuoco reportedly said that she’s looking for a motivated man with a job.

Sweeting, a professional tennis player, has only won his first title back in 2011. His tennis career has been quiet since.
