Despite their complicated history together, Pink insists she wasn’t cringing during Christina Aguilera’s tribute to Whitney Houston at the American Music Awards in Los Angeles on Sunday.

“Yes. THIS. Christina f—ing killed it tonight for one of our favorite singers ever,” Pink wrote on Twitter as people criticized her reaction to Aguilera’s performance when the camera cut to her.

Pink continued: “This about Whitney, and I am in awe of Christina’s talent. Show the clip where I’m in tears, you negative Nancy’s ??✌?❤️”

Pink was seen applauding Aguilera’s medley — which included renditions of “I Will Always Love You,” “I Have Nothing,” “Run To You,” and “I’m Every Woman” from Houston’s soundtrack for The Bodyguard — after Aguilera delivered her last note.

The ladies achieved success together early on in their careers, finding a hit in a cover of “Lady Marmalade” with Mya and Lil’ Kim for the Moulin Rouge! soundtrack in 2001, but differences stemming from the collaboration led to an altercation: Pink explained to Andy Cohen on Watch What Happens Live in October that Aguilera “swung at me in a club.”

“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, later adding: “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.”

For Pink, the feud is water under the bridge. “She’s so talented and deep down I’ve had bad days, too,” she said. “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.”

Parenthood may have had something to do with the resolution. “We became moms. We grew up. We hugged it out,” said Pink. “It’s that simple. I feel so good about that.”

Meanwhile, Pink’s numbers at the AMAs are also hot topics online: After performing R.E.M.’s “Everybody Hurts” alongside Kelly Clarkson, Pink scaled the side of a building in downtown L.A. during a high-flying rendition of her single “Beautiful Trauma.”
