The Big Bang Theory co-stars Kaley Cuoco and Johnny Galecki are debunking rumors that they've rekindled their romance following Cuoco's divorce filing.
"So sorry to disappoint, but no home wreckers or secret flings going on here," Cuoco, 29, posted to Instagram on Wednesday. "Me and @sanctionedjohnnygalecki are just the best of buds -- Leonard and Penny will just have to suffice!"
The post seems to be in response to tabloid articles claiming that the former couple have become more than friends.
Galecki, 40, echoed Cuoco's sentiment in a post of his own, writing, "No scandals / home wreckers / pregnancies here, y'all. Just profound friendship."
Last month, Cuoco announced that she was divorcing her husband of 21 months, 28-year-old tennis pro Ryan Sweeting. The split came after she took to Instagram in April to deny whispers that she and Sweeting were growing apart.
"I have never been more proud of anyone on this planet," Cuoco wrote at the time. "This guy is fighting back from a whirlwind of injuries and not to mention constant 'conversation' regarding our marriage and basically any daily decision we decide to make."
Just days before the split announcement, Cuoco addressed what it was like working with an ex on her hit CBS sitcom, telling a caller on Watch What Happens Live that there is no awkwardness between them.
"Well, we dated like five years ago, so I think we both moved on," she said. "Johnny is actually one of my best friends. It's a situation that ended well. I understand sometimes it doesn't. It could have gone horrible."
Cuoco continued to sing Galecki's praises, revealing that he even got along with her husband. "He's one of my dearest friends and Ryan loves him. Johnny loves [Ryan]," she said. "I got lucky."
As for the divorce, a source close to Sweeting told ET, "It didn't come out of left field or a shock to anyone close to them ... it was a long time coming."
"She realized she wants to be with a guy who has a job and is motivated," our source added. "All of Ryan's friends knew it was going to end bad."
Sweeting, who turned pro in 2007, won his first and only title in 2011, when he beat Kei Nishikori of Japan at the U.S. Men's Clay Court Championships in Houston.
