Megan Fox wants to know everything about Machine Gun Kelly - even the littlest things.

Even before Fox and MGK got engaged, the couple spent time getting to know each other. In fact, the actress once asked him something unusual.

In an exclusive interview with E! News during the red carpet of MGK's Hulu documentary "Life in Pink", Fox revealed that she asked the singer if he was breastfed by his mother.

Although it shocked their fans, the "Jennifer's Body" actress explained that she had to ask it to learn more about his psychology and temperament.

"If you know me and I know you, it's impossible for me to not know almost everything about you," she said.

Fox added that she wants every question to lead her to deep conversations instead of learning simple things, like favorite colors or films.

Indeed, her curiosity and desire to learn things about her beau paid off already. For what it's worth, she perfectly answered during their quiz for British GQ.  At that time, she answered everything about MGK - his astrology sign, shoe size, nickname, favorite things, and more.

Because of her knowledge, even the "Emo Girl" hitmaker praised her, telling her she would win every single category if she was his "Jeopardy!" partner.

Machine Gun Kelly Also Romantic Toward Megan Fox

Unlike Fox, MGK seemingly has a different way of showing his love for the actress.

In a separate interview with E! News (via Hola!), Fox said that being able to listen to her is the most romantic thing MGK does for her.

"I mean, over the course of two years, we have a lot of a lot of things that we've done together. He's just a very romantic boy, so I have a lot of stories," she said.

For instance, MGK reportedly gifts her with the things she mentioned during the first time they met since that memory never went away.

With that, she thought it was the most romantic thing he did - and still does.

But aside from being romantic, they also shocked the world when they had a blood-drinking ritual. They did it as Fox is into astrology, metaphysical practices, and meditations. She is also fond of new and full moon practices.
