Little Mix's Perrie Edwards has changed a lot since getting engaged to One Direction's Zayn Malik. Now she farts and bites her nails in front of her fiancee. We don't make this stuff up.

Perrie Edwards and Zayn Malik got engaged last August and since then the Little Mix singer has gotten a lot more comfortable around her One Direction boyfriend.

According to Cambio, during a recent interview with Now magazine, Perrie said, "Zayn's fully aware of what periods are and I don't think he's really bothered."

Little Mix bandmate Jesy Nelson explained: "Perrie will happily fart in front of Zayn but I'd never do that in front of Jordan. Never. I'd go outside and fart instead. I wouldn't do it in front of my boyfriend because if he did it in front of me, it would really put me off and make me feel sick."

Perrie explained, "I do it because I'm engaged. But if I wasn't engaged, I'd be kind of f**ked. I bite and chew my nails in front of him, too."

Sometimes it's good to leave a bit of mystery to a relationship, Perrie.

So what's the secret behind her relationship to boyfriend Zayn Malik?

"I'm not a kind of 'in your face' person and neither is Zayn, so we just work. We have a good balance. When we're hyper, it's great, and when we're not it's great - it's the perfect balance...Always keep them on their toes, that's the main thing," she told Now magazine.

Perrie Edwards, 20, recently dished about her wedding plans to One Direction singer Zayn Malik, 21.

"I definitely want long sleeves. I know exactly what I want, so I'm designing it and getting it made from scratch," Perrie Edwards told the Daily Mirror.

But which Little Mix singer will help Edwards design her wedding dress?

"Not that I can draw. I'm getting Jade to do it. She's going to draw it and I'm going to take it to somebody to make."

We can't wait for these two pop stars to get hitched!
