18. Leonardo DiCaprio
In an interview for Movieline Magazine in 1995, Leonardo DiCaprio shared the most embarrassing details of his first kiss. He was recorded as saying, “It was the most disgusting thing in my life. The girl injected about a pound of saliva into my mouth, and when I walked away, I had to spit it all out. It was awful.” It seems that Kate Winslet was a better kisser because Leonardo seemed comfortable kissing her while filming the movie, Titanic.
