Kaley Cuoco is once again being forced to defend herself against pregnancy rumors following a joke by her The Wedding Ringer co-star Josh Gad.

While appearing at the Night at Sardi's Benefit for Alzheimer's on March 18, the actress hijacked Gad's interview with E!'s Ali Fedotowsky-and after Gad made a comment about her future children, Cuoco was left having to defend herself and deny the rumors once again.

"Once your children have their baptisms and whatever, I'm going to be their hired entertainment," he said.

"Children?! Wait, Josh, did you just give away that Kaley's having children?" Fedotowsky asked.

"I did! Kaley's having children!" Gad joked. "Can I tell them please?"

Cuoco then shook her head, simply saying, "He's a liar. Such a liar."

Gad then ended the joke, admitting he wouldn't have known first anyway because Cuoco didn't talk to him on a normal basis.

""We don't talk, she doesn't return my calls," he said.

However, even after her joking co-star left and she was joined by her sister, Brianna, Cuoco still needed to address the pregnancy rumors, after Fedotowsky, who is one of her friends, reminded her that she couldn't be pregnant because they had made a pact to have children at the same time.

"Josh Gad just told E! that I was pregnant, so if it comes from Josh Gad's mouth, you know it's a blatant lie," she said. "No, I'm not pregnant! I don't know why people keep thinking that. Maybe I should wear a little tighter clothes."

But though she isn't yet pregnant, Cuoco assures that she and Sweeting aren't ruling babies out in the future.

"You never know," she said. "We're practicing a lot, so you never know!"
