Kaley told the new issue of Cosmopolitan US that she'd managed to survive in the showbiz industry for 20 years without being photographed in public – until she met hunky Henry.
"I had no one following me until I met Superman," she said.
"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 several months ago. The recognition was crazy."
(Still, she got to date Henry Cavill!)
According to the mag, the courtship between Kaley and Henry lasted just ten days before things cooled off.
Now Kaley, who plays Penny in Big Bang, is happily married to tennis player Ryan Sweeting, who popped the question in September 2013, just three months after they were introduced through friends.
They married just three months later in a fire and ice-themed ceremony held on New Year's Eve, where Kaley wore a pink wedding dress and guests ate an upside down wedding cake. Really!
"What was amazing in that room, it was so full of love. It was like nothing I'd ever been to before, and it was exactly what we wanted it to be. It was the eighth wonder of the world, the greatest wedding of all time."
One of the guests at her wedding was Big Bang Theory co-star Johnny Galecki (Leonard). Kaley and Johnny dated in secret for nearly two years, but only made that information public knowledge in 2010 when they'd split.
Recounting how they moved on, Kaley said: "It took a minute, a bit of awkwardness. By the grace of God, we became best buddies and moved on in such an elegant way. [He's] one of my closest friends. He was in the front row at my wedding, with a huge smile on his face."
Kaley's issue of Cosmopolitan US hits newsstands on 8 April.
