Close shave for Olivia Newton-John! Cancer survivor helps Las Vegas locals 'brave a shave' at charity fundraiser before cuddling up to buff Chippendale male dancers

Currently living in Sin City for her residency at Flamingo hotel and casino, Australian icon Olivia Newton-John was occupied with good deeds on Saturday.

The 66-year-old cancer survivor got involved in a fundraiser held at New York, New York hotel for children's cancer charity St Baldricks and shaved the head of a local participant.

Greg Chase, Director of Guest Experience for the hotel looked a little nervous in his dark green styling cape as the music legend grabbed the clippers in hand.

Starting at the base of his neck and working his way up, the blonde Aussie beauty laughed as she shaved a Mohawk into the top of his brunette hair.

But the edgy look didn't last long with the performer finishing off the job and proudly pointing to Greg's bald shaved head.

As Olivia waved to the gathered cameras, the pair both looked happy with how the close shave went.

The Grease star left her brown sunglasses on for the outdoor haircut, given the sunny spring day.
