Pink Versus Christina Aguilera
Although Christina Aguilera has become known for calling out her rivals, it was Pink who made this feud public. After recording Lady Marmalade together for the Moulin Rouge soundtrack, Pink stated that Aguilera had demanded that she have the most prominent section of the song, which Pink objected to. A few years later, Pink’s writing partner, Linda Perry, collaborated with Aguilera on her hit Beautiful. Pink was angry, telling MTV, “I took it really personally when [Perry] started working with other artists, particularly artists I didn’t like.” Years later, Pink threw a jab on Twitter when Aguilera was arrested for public intoxication. She also mentioned that Aguilera had tried to punch her in a club in the early 2000s. In 2016, the two reunited and worked together on The Voice. Pink even suggested that they might collaborate on a song.
Mick Jagger Versus Keith Richards
This feud unfolded over the course of decades, with Mick Jagger and Keith Richards insulting each other, fighting, and making up seemingly dozens of times over the years. During the 1970s, Richards was lost in a haze of drugs and alcohol. Meanwhile, Jagger was becoming an icon and shaping the sound and look of the Rolling Stones. Richards took issue with some of this direction, but Jagger refused to relinquish control. In the 1980s, Jagger went solo, which made Richards furious. The group broke up for several years. Eventually, they mended bridges and reunited. However, in his 2010 memoir, Richards wrote that Jagger had a small penis, and he bragged about sleeping with one of Jagger's former girlfriends. Conveniently, Richards apologized for the book just in time for a Stones reunion tour.
