Kate Winslet speaks out over 'nightmare' experience kissing Leonardo Dicaprio

Those who crushed on DiCaprio back in the day *look away now*, as his famous co-star has revealed what it was really like kissing the actor on set.

The 1997 film saw seventeen-year-old aristocrat Rose DeWitt Bukater (Kate Winslet) fall in love with a poor artist (Leonardo DiCaprio) aboard the ill-fated R.M.S. Titanic.

As we are all aware, the James Cameron movie was huge success, racking up 11 Oscars, including Best Picture.

“I do feel very proud of it, because I feel that it is that film that just keeps giving,” Winslet recently told Vanity Fair.

“Whole other generations of people are discovering the film or seeing it for the first time and there’s something extraordinary about that.”

Now, during the iconic 'I'm Flying' scene, Winslet has opened up about the sheer amount of makeup the pair had on, making it a bizarre kissing experience.

“My god, he’s quite the romancer, isn’t he? No wonder every young girl in the world wanted to be kissed by Leonardo DiCaprio,” Winslet joked.

“It was not all it’s cracked up to be.

“We kept doing this kiss, and I’ve got a lot of pale makeup on and I would have to do our makeup checks — on both of us, between takes — and I would end up looking as though I’d been sucking a caramel chocolate bar after each take because his makeup would come off on me.”

As she rewatched the scene, the Academy Award winner quipped: "Oh God, it was such a mess.

“This was a nightmare.

“Leo couldn’t stop laughing, and we had to reshoot this about four times because [director James Cameron] wanted a very specific light for this, obviously, and the sunsets kept changing where we were.

“This was a section of the ship, it wasn’t part of the actual whole ship set that we had.

“We had to climb up a ladder to get to it.

“Hair and makeup couldn’t reach us. Now, what you wouldn’t know because Leo looks completely natural but he had to lie on sunbeds and there’s a lot of fake tan makeup going on.”

A couple of months ago, the actor appeared on the Chris Evans Breakfast Show, revealing that she was in a brief relationship with her The Holiday co-star Rufus Sewell, 56, who recently played Prince Andrew in Netflix's Scoop.

Gillian Anderson stars as BBC journalist Emily Maitlis, as Winslet added: “No. But I bumped into Gillian Anderson at an event not very long ago, and I was asking her about it."

She then said: “And Rufus Sewell is so terrific, you know, I used to go out with Rufus Sewell years ago.

"Back in the day, a long time ago, I think I must have been 21 or something.

"He's so fantastic and to see him front and centre in a way that I think we haven't done on British television for a long, long time, very long time, I'm really, really excited to see what he does.”

Winslet has been married to Edward Abel Smith since 2012.
