DIVAS Prinnie Stevens and Mahalia Barnes of The Voice fame will headline The Hills News Hills M2 Run for The Hills festival.
The two friends, who battled it out in one of the most talked-about and emotional episodes on Channel Nine's first series of The Voice, will be at The Hills to support this fund-raising activity for babies and preschoolers with a disability.
"As a mother myself, I know how hard it can be with kids," Ms Stevens said. "I support such a great cause that helps parents with children with disabilities by giving them access to vital intervention services."
The inaugural Run for The Hills — an eight-kilometre fun run and festival in the heart of The Hills — is the major fund-raiser for the Reach for the Rainbow charity and will be held on Sunday, October 7.
The charity was founded by people's choice Woman of the Year Yvonne Keane and raises funds to support babies and preschoolers with a delay or disability by giving them access to early intervention services.
Ms Keane aims to fund the world's first early intervention hub where families can access comprehensive specialists and services at little or no cost.
Castle Towers will host a festival after the fun run with carnival rides, an animal farm and a huge AMF Bowling set plus the special performance by Prinnie and Mahalia at Arthur Whitling Park Castle Hill and the main street.
Marketing manager Andrea Maguire said Castle Towers was proud to support the event.
"I encourage everyone to take part in this extremely worthwhile event and to join in the fun for the day," she said.
