Speaking to 'Extra', the actress explained: "For every person who knows Jamie, like, it was terrifying.

"For everybody who loves Jamie, the world, like, everybody was concerned ... I can't even imagine how he feels.

"I'm so proud of him, how brave he was to do his [stand-up special], to let us all know. But you know, it's hard. You walk up to him and he's like, 'Everybody cries'!"

Cameron ended her self-imposed acting hiatus to star in the new action-comedy film, and Jamie has now revealed how he convinced his showbiz pal to board the project.

He shared: "Listen, we were very humble in our ask. We were very respectful in our ask.

"There was a couple of promises. I was like, 'I don't want your feet to touch the ground. I want this to be fun thing for for you to do.'"

Cameron, 52, praised her co-star for upholding his end of their agreement.

The actress also hailed Jamie as the "most talented man in showbiz".

She said: "Even with that promise, which he upheld, he did take such good care of me.

"It was really about the fact that I knew that if I was going to leave ten hours a day, leave my family, that I was gonna get to do the work with the most talented man in showbiz. Professional, a fantastic partner.

"I knew that it was gonna be worth my while to go no matter what and that we're going to have fun."
