Behind Pink's badass attitude is a reformed slut. The U.S. pop star unapologetically owned up to her past behaviour and claimed that *NSYNC singer Joey Fatone was once in love with her, while demanding flowers from her husband.

Speaking to Glamour magazine, in which she graces the cover of its June issue, the likeable 33-year-old "Just Give Me a Reason" singer admit that the sex songs on her album are her way of rebutting the notion that women who sleep around are sluts, while the men who do the same are players.

"I'm a reformed slut," she candidly told the magazine. "It's my very unsophisticated way of taking the power back. I've always had an issue with [the idea that] 'OK, we've both decided to do this. Why am I a slut and you're the player? You didn't get anything from me that I didn't get from you."

Pink, whose real name is Alecia Moore, also recalled how she got on a date with Joey while she was on the road with *NSYNC.

"Joey Fatone was in love with me. He took me to Friendly's on a date, and he bought me an ice cream. Such a sweetheart. He asked my dad's permission."

But that was all in the past. Pink is now happily married to now-retired motocross racer Carey Hart, with whom she has a 2-year-old daughter. Not everything's peachy in their marriage, though, and that's fine. The couple separated in 2008 after two years of marriage, but got back together in 2010.

"Are things ever good? I don't believe that exists. Long-term relationships are everyday choice. It's harder to be in a marriage than it is to bounce from one relationship to the next. We're good because we communicate and we've grown together, not because we don't fight."

When asked what was the last thing they fought about, Pink yelled to the next room, calling, "Carey! What was the last thing we fought about? Oh, I know! You not getting me flowers and being a douche bag. That was it.

"He needed to get me flowers after I had a big show. Hear that, Carey? I'm throwing you to 17 million wolves [Glamour readers] right now, buddy."

Her tough girl persona isn't just an act. And not even motherhood has calmed her down. If anything, she has became tougher now that she has her daughter.

"Somebody asked Carey how I've changed since I had Willow, and he said my claws have sharpened. They got longer, too."

About their daughter, Pink explained how they got to her name Willow Sage, saying, "I love the idea that a willow tree cannot be snapped or broken. And we burn sage all the time. It clears bad energy."

She needs to be more careful with her language around Willow, though.

"Willow said, 'F-kin' hi,' the other day. I'm like, 'F-k! Yes, we're gonna get a jar. Have to."
