"Grease" alum Didi Conn is proving she still goes together with co-star Olivia Newton-John, more than 40 years after the iconic movie musical. 

Speaking on the British talk show "This Morning," Conn sang Newton-John's praises as her former co-star battles cancer. 

"The best news I've heard is that Olivia Newton-John is doing beautifully well," Conn said. "Her spirit shines. We just love her... Her husband is this miracle maker of growing different herbs and the cannabis is really working for her with the pain. And he's gorgeous and they're in love, and love always heals." 

The "Physical" singer was first diagnosed with breast cancer in 1992. In 2013, doctors found cancer in her shoulder after she was involved in a car accident, a diagnosis Newton-John did not reveal to the public until years later. Most recently, she revealed her breast cancer metastasized to her lower back in 2017. 

Conn played Frenchy opposite Newton-John's Sandy in the 1978 classic and says she's still in contact with the cast today. 

"In the movie, we said 'we'll always be together,' and you know what? We've made friends that have lasted 40 years," she added.
