Pink discussed her previous feud with fellow singer Christina Aguilera Thursday while appearing on "Watch What Happens Live" with host Andy Cohen.

"We were super young and super new at the whole thing, and I think I'm an alpha, and she's an alpha," Pink said of the feud that took place in the early 2000s during the show's Plead the Fifth segment.

"I'm used to taking my altercations physical and she's used to having them verbal. We're just very different, we're very different. And we were very young and new," the pop star continued before mentioning how Aguilera once tried to punch her.

"Actually, she swung at me in a club. Hilarious!" Pink said of an altercation they had inside of a club. "I was like, 'What's happening right now? What's happening?'"

Pink and Aguilera reportedly clashed over song "Lady Marmalade" and argued over who would sing the highest notes on the track, People magazine reported.

The pair have since made up, however, with Pink stating that they shared a hug while appearing on The Voice.

"We became moms. We grew up. We hugged it out. It's that simple. I feel so good about that," Pink said.

Pink will be hitting the road again as part of a new 40-date North American tour in support of new album, Beautiful Trauma.
