Money raised at the Swan Yacht Club event on Sunday, February 7, will go towards several charities.
Mrs Everall said she met Ms Watts through a friend about 12 years ago and started helping out at her events.
She said the charities she supported were close to her heart.
“I look forward to the events because they’re all so different,” Mrs Everall said.
Soon after, Mrs Everall started bringing her mum Mrs Clive along to events.
Mrs Clive is now a regular at the fundraisers.
“Everyone always enjoys themselves,” she said.
International recording artist Ric Stern will perform with vocalist Alexandra Hainsworth at the event.
The duo, known as The Entertainers, perform music from various genres.
