Olivia Newton-John's death shocked the world.

Not because she was totally unexpected (she was diagnosed with breast cancer in 1992 and she never hid her long-term battle with the disease) but because the star is forever associated with youth and freshness of his cult character Sandy in

Grease

, released in 1978.

Obviously upset, her costar from the musical, John Travolta, paid tribute to the actress on Instagram.

“My dearest Olivia, you have made all of our lives so much better.

Your impact has been incredible.

I love you so much.

We'll see you later and we'll all be together again.

You are mine from the first moment I saw you and forever!

Your Danny, your John!

“, he posted.

First love

“I loved

Coincidentally, I also bought and lived for a time in the beautiful house she had built in Malibu.

Viola Davis also paid tribute to Olivia Newton-John by recalling the impact she had on her time with the iconic role of Sandy.

“You were my childhood!!

Your talent, your presence, your beauty!

Rest in peace.

God bless your family….

and thank you for creating eternal memories,” the Color of Feelings

star posted

, while American singer Richard Marx mourned the loss of a close friend.

Rest now, dear friend.

You were as kind and loving a person as there ever was.

I will miss you every day.
