Pink and Christina Aguilera may have recently put their feud to rest [1], but their beef was once so bad that Christina actually tried to punch Pink at a club. During an appearance on Watch What Happens Live on Thursday, the "What About Us" singer [2] opened up about what went wrong with their relationship after they collaborated on "Lady Marmalade" in 2001. "We were super young and super new at the whole thing, and I think I'm an alpha, and she's an alpha," Pink explained during Andy Cohen's "Plead the Fifth" segment. "Actually, she swung at me in a club. Hilarious!"
Christina and Pink allegedly clashed over who would sing the high notes on "Lady Marmalade," but Pink insists they are fine now. "She's a really sweet person. We made up on The Voice. I mean, it was funny; I laughed. I hadn't seen her in years and years and years." She also hinted at a possible upcoming collaboration with Christina [4], so we're keeping our fingers crossed.
