It seems that Johnny Galecki and Kaley Cuoco are back on the dating scene as the duo were recently seen cuddling in between takes of "The Big Bang Theory" season 10.

The 41-year-old actor recently shared a sweet photo with his "The Big Bang Theory" co-star while they were on the set of the hit sitcom. On his Instagram account, Galecki posted a black-and-white snap of him and Cuoco cuddling in between takes.

The black-and-white snap made some fans think that Galecki and Cuoco are back together. It can be recalled that the two dated each other for around two years until December 2009.

This is not the first time that the ex-couple created some excitement online. While at the 2016 People's Choice Awards, Galecki and Cuoco were spotted holding hands and embracing each other, as per Entertainment Tonight.

At the time, Cuoco shared an image on her Instagram account and used the hashtag #NotDating to shut down the dating rumors.

Currently, Cuoco is in a relationship with Karl Cook, a professional equestrian rider. In a sit-down interview with "CBS This Morning," the actress gushed about her new beau.

"He is special," said Cuoco. "I think that the horse connection is special."

The actress also opened up about her divorce with professional tennis player Ryan Sweeting. The estranged couple got married on Dec. 31, 2013, in Santa Susana, California and shortly called it quits in September 2015.

"You know what, I'm not ashamed of anything that happened," said Cuoco. "I fall in love really hard. I go deep and that person is it for me. I love hard, and when it is over, it's over. Some people make mistakes, and I wouldn't call it a mistake - it's just what happened in my life and now, I'm excited to see what the future holds."

Meanwhile, the tenth season of "The Big Bang Theory," which co-star Johnny Galecki and Kaley Cuoco, will start airing on Sept. 19.
