But now we’ll take a look at who Johnny has dated in bygone days…

Johnny and make-up artist Lori were married 1983-5.

“You know, I was married when I was 20. It was a strong bond with someone, but I can’t necessarily say I was in love. That’s something that comes around once, man, maybe twice if you’re lucky. And I don’t know that I experienced that, let’s say, before I turned 30.”

Johnny and Sherilyn met on the set of a student short film in 1985. The couple got engaged, and Sherilyn’s name is scrawled across Johnny’s helmet in the 1986 film Platoon. They broke off their engagement after three-and-a-half years.

Johnny has a habit of dating his co-stars, including Holly in 1987 who he acted alongside in TV series 21 Jump Street.

Johnny has been romantically linked to Dirty Dancing star Jennifer.

Winona is another co-star Johnny has dated, performing together in Edward Scissorhands.

The two were engaged, and Johnny had “Winona forever” tattooed on his arm. After they broke up, he had “na” removed so the tattoo said “Wino forever!”

Johnny dated actress Ellen in 1994.

Kate and Johnny were on-again, off-again for years. Here they are in 1995.

Johnny’s been linked to a long list of other actresses, including Christina…
