Margot Robbie says kissing Jared Leto on set was "messy"

And it's all down to lipstick

While we never would have thought kissing the gorgeous Jared Leto could be anything but perfection, Margot Robbie gave the inside scoop on what it was really like to make out with Leto on the set of Suicide Squad — and, trust us, it was actually quite a mess.

Robbie, who plays Harley Quinn, all-around badass and the Joker’s love interest, told PEOPLE, 'It’s so messy,' she said, 'I’ve done kissing scenes where I have lipstick on and that’s a nightmare, but to have two of you having the lipstick on, it’s terror.'

When everyone involved in a smooch is all done up, it’s takes a whole ‘lotta talent (and a pretty mechanical move) to keep the kiss clean. A full face of makeup like what the Joker and Quinn rock on set? We shudder just thinking about it. Take a look through Margot Robbie's beauty look book, if Harley Quinn's signature style isn't your thing.

Luckily, though, Robbie wasn’t too freaked out by the kiss, or by Joker’s intense makeup: 'Once you get over the initial shock of meeting Mr. J, you kind of become desensitized to it I guess so it seemed normal after a while.'

Robbie knows how to brush off the little things, and why wouldn’t she? The talented actress has been in hit films like The Wolf of Wall Street and About Time, and is slated to be in the highly-anticipated, but currently untitled, Harley Quinn project that’s been in the works since May.

In comparison? A little lipstick is nothing.
