Angela revealed that Erin was "plucked from a Sydney beach to star in an international tourism campaign" at the start of her career.
"Then Aerobics Oz Style watched by 40 million people around the world. As Erin told us in 2016 when we had a special aerobics All-Star reunion," said the showbiz reporter.
