Kaley Cuoco Hilariously Reacts to Question About Ex Henry Cavill's 'Man of Steel' Body

Kaley Cuoco and Henry Cavill were romantically linked for a brief time back in July 2013

Kaley Cuoco's lips are sealed!

During an appearance on Tuesday night's episode of Watch What Happens Live, the 35-year-old actress — who briefly dated onscreen Superman Henry Cavill back in 2013 — was asked to respond to fan question about whether "the Man of Steel" is "really made of steel."

"Oh my God," she replied, laughing heartily before replying, "I don't know. I never say, 'I don't know' — I always have an answer — but I don't know."

Cuoco and Cavill, 37, were romantically linked for a brief time back in July 2013. PEOPLE confirmed just 12 days later that the two had called it quits.

i really dislike her smirky, sidways smile. it bugs.

I don’t know her work that well and didn’t watch her sitcom, but I thought she was excellent on Curb Your Enthusiasm. She played Vince Vaughn’s character Freddie Funkhouser’s girlfriend, the optometrist. They have an argument about Larry David’s character, and she delivers the line “This is all fuckin’ LARRY DAVID!” pitch perfectly.

That relationship was so random and so obviously fake, it was comical.

I like her. She has great comedic timing and delivery.

Wonder if she has since fired the publicist who came up with that lame charade with Henry.

Here’s the thing

Warner Bros was TERRIFIED when they hired Henry

I remember within hours of the Superman casting being announced on Deadline, the headline was revised to add the word “macho”

Ie “English actor Henry Cavill is cast as Superman” became “Macho English actor Henry Cavill…”

As Cuoco was also working for Warner Bros at the time, it was likely the studio that arranged the grocery store outing
