Let's be honest, we all know John Travolta and Olivia Newton-John go together like "rama lama lama ka dinga da dinga dong."
Ever since the pair starred alongside each other in 1978's hit musical film Grease, they have held a special place in their fan's hearts.
And now, it's looking like they might be joining forces again.
While walking the red carpet at the Los Angeles premiere of his new movie, The Fanatic, the 65-year-old delighted fans when he hinted that there might be a collaboration in the future.
As he opened up about his close friendship with Olivia, he said: "We were together not that long ago, about three months ago, and we text each other all the time."
"It's wonderful ... If I go to see her in her show, we go backstage and hang out, and I watch the show and all that. If I go to see her personally, we usually have dinner and catch up. And recently we've been talking about trying to do something together."
Whether this "something" is new music or a movie, we're sure it will be amazing!
Of course, Olivia has been taking time to focus on her health after announcing her third breast cancer diagnosis in September 2018.
During his red carpet interviews, John also praised Olivia for her strength throughout her cancer battle.
"She's doing great," John said. "And she looks fantastic! I'm so proud of her ... she's pulling it off like I've never seen anybody [do]."
