Kate Ritchie reveals secret of Home and Away co-star.

Actress Kate Ritchie, 36, has dropped a bomb on one of her Home and Away co-stars while live on radio.

A poo-sized bomb.

The mum explained one of her cast mates used to laugh about defecating into holes at golf courses. That’s right, they used to take a dump in the holes.

“They used to go in the middle of the night and do that in the holes so that when people got a hole in one, they would reach in,” Ritchie told fellow Nova hosts Marty Sheargold and Tim Blackwell.

While Ritchie wouldn't out the person, she did say that they were a male.

“You would know who this person is. They are very famous and you know them from the TV. They told me that story when I was a child to impress me," Ritchie continued.

When questioned further, Ritchie ruled out Ray Meagher (who played Alf Stewart), Josh Quong Tart (who played Miles Copeland) and Daniel Amalm (who played Jack Wilson).
