"The Big Bang Theory" star Kaley Cuoco and Johnny Galecki recently sparked dating rumors after they were spotted on a night out in Los Angeles on Friday night.
Cuoco and Galecki also shared photos from her rendezvous, and fans couldn't help but notice how adorable the estranged couple looked.
On Galecki's Instagram account, the actor shared a photo of himself biting Cuoco's right shoulder. Cuoco looked like she had so much fun in that very moment.
"Hilarious night out in the LA Arts District w/ @normancook #BFFsbite @ludwig1965 @bricuoco," he wrote.
Cuoco also shared a photo of herself with Galecki and her sister.
"So fun tonight! #fallout4party," she wrote.
Meanwhile, fans couldn't help but wonder what's the real deal between "The Big Bang Theory" co-stars.
Just recently, Cuoco divorced from her ex-husband Ryan Sweeting after 22 months of being married.
At that time, fans already speculated that Galecki might have something to do with the divorce.
However, Cuoco clarified that she and her co-star are just friends.
In an interview with E! News, an insider revealed that Cuoco and Galecki didn't show any signs of intimacy. In fact, the best friends were spotted together with their group the entire night.
"There was no PDA between them. They were just drinking and dancing with friends, and having a good time. They seemed to especially get excited when Bloc Party went on stage to play," the insider said.
At present, Cuoco's ex-husband Sweeting is seeking a $45 million spousal support from her.
