During an interview with Vogue UK, Kristen Stewart shared some intimate information about the "good old days" with Robert Pattinson and some might deem it as "Fifty Shades" weird. According to Stewart, her ex-boyfriend and fellow "Twilight" co-star used to love to lick under her armpits.

Keep in mind that this statement didn't come from a source, insider or friend; it came straight from Kristen Stewart's mouth to Vogue UK.

She said, "I love the way [Robert] smells. And him me. Like, he loves to lick under my armpits."

"I don't get this obsession with washing the smell off. That smell of someone you love. Don't you think that's the whole point?" Stewart said to the fashion magazine.

Why is this information just being released now? iSubscribe wrote that the interviewer from British Vogue, Christa D'Souza, listened to the tapes from the interview again and then heard Stewart mention the armpit licking in an unguarded moment.

Loving the way your lover smells make sense; one normally has an intense attraction to the individual. But licking under someone's armpits and liking it, that seems a bit much.

Christian Grey didn't stop at anything with his sex goddess Anastasia, except for tasting her underarms, that is. The "Fifty Shades of Grey" series flew off the shelves, with women everywhere secretly reading and fantasizing about Christian Grey's red room of pain and Ben Wa Balls.

But there has to be a line somewhere, and it seems the former lovebrids definitely crossed it.

It seems like Stewart can't keep Robert Pattinson off her mind if she's still talking about him post-break up in a Vogue UK interview.

The actress has two new movies coming out, the last installation of the "Twilight" series, "Breaking Dawn: Part 2" and "On The Road." Her reps must have been pretty upset when they found out she was talking about her underarms instead of her new movies.

Even though the stars are no longer in a relationship after Pattinson found out that she had been unfaithful, the two will appear together to promote the last "Twilight" movie.

She reportedly said that she would be "fine" and that her and Pattinson are "totally fine."

But working together again might be even more awkward now that the world knows they used to love to lick each other's armpits.
