The COLUMBO actor was reportedly so frustrated with her lively antics and hyperactive personality that he lashed out at the young Lloyd.
The blonde actress says, "I was larking around on set and that annoyed Falk because he was such a methodical actor. So he hit me.
"I didn't burst into tears or feel sorry for myself - I slapped him back. He was stunned and walked off.
"But I have always been feisty and spoken my mind. That is the way I have been brought up and I'm proud of it."
