Michelle Pfeiffer & 'Grease' Star Olivia Newton-John Shared Sweet Moment at the G'Day USA Gala 2020 in LA

Olivia Newton-John may not have thought much of "Grease 2," but she and Michelle Pfeiffer shared sweet moments in Los Angeles when they attended the G'Day USA Gala over the weekend.

In aid of the Australian Bushfire Relief Fund, G'Day USA held a gala on Saturday night, and the two actresses looked stunning for the event.

61-year-old Michelle Pfeiffer looked stylish in an oversized white blazer, while Olivia Newton-John strutted the red carpet in a black patterned blouse and trousers.

"Look who I ran into last night - the original Pink Lady," Michelle captioned a slideshow of images taken during the evening as she and 71-year-old Olivia snuggled up together and held hands.

Olivia, who attended the event with her husband John Esterling and niece Tottie Goldsmith, reposted the same sweet snap, and she shared how "lovely" it was running into the "Grease 2" actress at the gala.

"Denial is a wonderful thing."

Michelle Pfeiffer took over Olivia Newton-John's character for the second "Grease" film. During an interview on "Watch What Happens Live with Andy Cohen" in 2016, Olivia shared that she didn't think much of the second movie.

Recollecting that she and John Travolta initially got approached to reprise their roles, the project almost fell through a few times before they settled on another cast, which became Olivia's "memory of it."

John Travolta and Olivia Newton-John became close friends since they co-starred in "Grease" all those years ago, and he also attended the gala in support of his friend, who is battling stage-four breast cancer.

At the gala on Saturday, Olivia reportedly told Daily Mail Australia that "life is a gift," and that she wants to help other sufferers of the disease and added:

"I am winning over it and living with it well. I don't think about it a lot to be honest. Denial is a wonderful thing. I am getting stronger and better all the time."

Since Olivia first got diagnosed in 1992, she maintained a strong and positive outlook on her health and life. Determined to make a difference, Olivia teamed up with Dancers Against Cancer in August last year.

The organization aids choreographers, dance educators, dancer, and their families who felt the impact of cancer, and it has raised over $2 million for the cause.

The actress appeared on a PSA shoot for the campaign and told PEOPLE that her health has improved, that she is "thriving" and "doing well."

Not one for buying into statistics, Olivia Newton-John previously told Gayle King that it could make a person "really nervous." She went into remission twice before. After her diagnosis in 1992, it went into remission but returned in 2003.

In 2017, Olivia learned that her breast cancer came back with a vengeance in the form of stage 4 metastatic cancer. Despite its return, she never asks why it's happening to her; instead, Olivia focuses on the life she wants to live.
