These days, thanks to a reconciliation engineered by tandem appearances on The Voice, Pink and Christina Aguilera are pals, but it wasn't long ago that they loathed each other, and in a new interview on Watch What Happens LivePink said Xtina once went as far as to try to hit her.

In a segment from Andy Cohen's "Plead the Fifth" game Thursday night (October 19), Cohen asked Pink to explain her feud and subsequent ceasefire with Aguilera in a little bit more detail. And while Pink said she was typically the type to bypass words and settle arguments with a little...uh...physical confrontation, it was actually Christina who took the first swipe.

"I'm used to taking my altercations physical and she's used to having them verbal — we just were very different," Pink said. "[But] she swung on me in a club. It was hilarious. I was like 'What's happening right now?' But we're fine. She's so talented. Deep down, I've had bad days too, but she's a really sweet person."

"We were super young and super new at the whole thing, and I think I'm an alpha and she's an alpha," she added. "Women have to learn how to support each other, it's not taught to us on the playground."

And Pink and Xtina are in such a good place now, that Pink said they've recorded new music together.

"We may or may not have already collaborated," she told an inquisitive caller. "I don't know if I'm allowed to say that but I just did."
