When "The Big Bang Theory" star Kaley Cuoco recently divorced her husband of one year Ryan Sweeting, a lot of people began hoping that she might rekindle her former romance with ex-boyfriend and co-star Johnny Galecki.

After all, their on-screen characters Leonard Hofstadter and Penny have just tied the knot and are enjoying wedded bliss (despite the temporary hiccup during their wedding night, when the couple fought about Leonard's kiss with another woman).

Many even suspected right away that the two have already began dating, even before Cuoco got into a divorce.

"Kaley has a special bond with Johnny, an intensity she never had with Ryan," reported HollywoodLife.

But Cuoco and Galecki are both sick and tired of the rumors, so they took to their Instagram accounts to tell the world once and for all that they are not in a relationship.

In Galecki's social media account, he posted a photo of himself sitting beside Cuoco, who had her arms up in an I-don't-know gesture.

"No scandals / home wreckers / pregnancies here, y'all. Just profound friendship," Galecki, 40, posted.

As for Cuoco, she shared the same photo, but only this time, she and Galecki are sharing a fist bump.

"So sorry to disappoint , but no home wreckers or secret flings going on here. Me and @sanctionedjohnnygalecki are just the best of buds- Leonard and Penny will just have to suffice!!!" Cuoco wrote.

Aside from Galecki, Cuoco has found a solid support system in the rest of her "The Big Bang Theory" co-stars such as Mayim Bialik, who plays one of Penny's best friends Amy Farrah Fowler.

"I think we're really blessed," the actress told E! News. "I think we're blessed more than people understand because I think when you hear that a cast gets along or functions like a family they think, 'Oh that's just lip service.'"

But Bialik said that their friendships are real, and they are trying to cheer Cuoco up by making her laugh.

"We love her to pieces and we give her as much joy and laughs as we give everybody who sees the stuff that we do but she gets to experience it off camera," Mayim said. "We spend more time with each other than we do with our own families, honestly. There's a lot of things you see in the press and there's a lot of things you don't see in the press that go on in our lives....but for the most part, we function like a really well-oiled family machine and we're grateful for that."
