Leonardo Di Caprio

The ‘Catch Me If You Can’ star, 49, almost drowned while scuba diving with his pal Edward Norton, 54, but the ‘Fight Club’ star saved the day.

Appearing on 'The Tonight Show Starring Jimmy Fallon', he said: "I give [my oxygen tank] to him. We did the buddy breathe thing and we go up, and he’s falling all over me, like ‘Buddy, buddy, you saved my life, you saved me.’ It didn’t seem dramatic to me, I think it did to him.”
