Olivia Newton John

 

Olivia Newton John was one of the first female singers to successfully undergo a complete image makeover from sweet and innocent country-pop singer with hits like I Honestly Love You, and Have You Never Been Mellow, to slightly more risqué pop singer Physical, Make A Move On Me. She starred as Sandy in 1978's Grease, where she originally exhibited her transformation from cute and bubbly goody-goody into a glamorous icon.
