Kaley Cuoco got a bit giggly when asked about her brief fling with Henry Cavill during a cheeky chat with Andy Cohen on the Watch What Happens Live! after show Tuesday night.

Reading a fan-submitted question, Andy asked: ‘Kaley, is the Man of Steel really made of steel?’

The Flight Attendant actress, 35, was blindsided by the question about the Superman actor, 37, who she dated for just weeks in 2013.

Funny: Kaley Cuoco couldn’t help but laugh when asked about her very brief relationship with actor Henry Cavill during an appearance on the Watch What Happens Live after show

Kaley couldn’t contain her laughter as she searched for a response: ‘Oh my God! I don’t know.’

She reminded Andy how rare that was, wagging a finger and saying: ‘I never say, “I don’t know.” I always have an answer, but I don’t know.’

Henry and Kaley were first linked on July 1st, 2013 but we’re seen cozying up together until two days later when they were photographed holding hands in LA.

But by July 11th, the pair reportedly split, according to reports from E! News at the time.

Talking about how her relationship with Cavill changed things, she told Cosmopolitan: ‘I had no one following me until I met Superman.

‘I’ve been in this business for 20 years, and my whole life, I could go anywhere, do anything. There had not been one paparazzi photo of me until like seven months ago. The recognition has been crazy.’

Kaley went on to wed tennis player Ryan Sweeting in 2014, but they filed for divorce in September 2015.

The Big Bang Theory actress has been married to equestrian Karl Cook since 2018.

During her chat with Andy, Kaley also revealed that creators of her show The Flight Attendant have a story prepped for a second season – if they’re called to do it.

Cuoco plays the title character in the new HBO Max series, in which her character wakes up in a hotel room one morning only to find herself in a pool of blood from the man she went to bed with the night before.

Kaley’s character flees and tries to go back to work as if nothing had happened, but the lingering fear that she might have murdered the man overwhelms her.

The first sevens episodes of the miniseries have already been released, with the finale set to air on Thursday night.
