Penny and Leonard weren’t the only ones drawn to each other on the CBS sitcomThe Big Bang Theory.

“I was so not even hiding it.

He has such swagger.

We were both dating people at the time, but I only had eyes for Johnny.

Galecki, for his part, was at first oblivious.

“I had zero idea of any sort of crush before Kaley and I began dating.”

Still, the onscreen chemistry that led to their offscreen romance was undeniable, Cuoco says.

“There was chemistry and we were crushing on each other.

That was the whole first season until we actually got together for real.”

“It was a whole thing, and it was a pre-tape since it took a little while.”

“Kaley didn’t look freaked out at all,” he says.

“In fact, she looked extremely happy in those arms.”

Cuoco adds, “I think we fell a little in love in that elevator shaft.”

Her costar says, “We felt something, yeah.

I think that was a massive turning point [in our relationship].

Lorre’s memory is a bit hazy: “I can’t remember that,” he says.

Post-split, the two remain on good terms.

(She and the latter divorced last year.)

“We adore each other.”

Galecki concurs: “We continue to love one another, just in other ways.”
