Nicki Minaj’s caught-on-camera rant at Mariah Carey featured a lot of yelling—and a lot of hot pink hair. Minaj is not the only pink-tressed celeb to go through not-so-rosy times. From Britney Spears’s infamous pink wig to Katy Perry’s rosy hair that preceded her divorce, see more stars who have us wondering: Is pink hair cursed? It’s no secret that Nicki Minaj is a fan of the color pink, so when she appeared in a video with her fellow American Idol judges this week with a cloud of neon pink surrounding her head, we thought all was well. But then the Young Money rapper launched into a largely unintelligible but apparently expletive-laden rant against fellow diva Mariah Carey—all of which got posted on TMZ.

The “Wide Awake” singer debuted the look at an event in Los Angeles on Dec. 5, and took many a cutesy photo with her then husband, Russell Brand. Within three weeks however, the two were spending Christmas apart and, by New Year’s Eve, the formerly happy couple filed for divorce. Coincidence? Perhaps not. Jason Merritt / Getty Images By now, people have heard that Amanda Bynes is not allowed to operate cars on her own anymore—a DUI, two hit-and-run charges, and getting caught driving with a suspended license (all within six months) will do that to a girl. But we suspect that more than just alcohol was at play during the DUI arrest that started it all—in the She’s the Man star’s mug shot, her hair looks just as guilty as her face. Getty Images Heidi Klum’s separation from her husband of seven years, Seal, came as a shock to some, but even more startling news came when Seal publicly accused his estranged wife of “fornicating with the help.” Klum and her bodyguard, Martin Kristen, have indeed grown closer, and made many public appearances together since her split from Seal. But what we take interest in is Klum’s choice of dyed pink tips right around the time of Seal’s accusations. Frederick M. Brown / Getty Images The X-Factor’s Season 2 judges include the inimitable combination of Demi Lovato and Britney Spears—Demi brings geometrically fascinating hair and Britney brings these faces. But did Demi’s pink dip-dye look foretell her misfortune on the second episode of the reality series? During a random bout of thunder and lights-out on set, Britney panicked and spewed soda on Demi, just missing her hair. Tim Mosenfelder / Getty Images Over the years, Kelly Osbourne’s hair color evolution has rivaled Katy Perry’s, including lavender, gray, and blonde hues. One of her most famous hairstyles, a pink pixie cut that she sported during her teens, also coincided with some of her lowest points. Since the age of 13, Osbourne battled an addiction to Vicodin, which eventually culminated in her time in rehab and the unraveling of her music career after she was dropped by Epic Records in 2003. Jason DeCrow / AP Photo Rachel McAdams knows all about playing the mean girl, but even she was bullied at an airport in 2007—and it was for the pink streaks she had at the time. Recounting the tale of her run-in with a pink-hating immigration official while reentering the U.S. from Canada, McAdams told The New York Times, “She was tough. I had pink hair at the time, and she said, ‘Don't dye your hair that colour and don't make any more stupid movies.’” Maybe it just wasn’t a Wednesday? Reed Saxon / AP Photo Britney Spears’ 2008 bald ’do is now infamous, but how many have forgotten the hot pink wig that came soon afterward? Spears spoke in a British accent while wearing the hairpiece and even reportedly took on other identities, right up until her father confiscated the wig. Spears’s then manager, Sam Lutfi, put it best when he said, “When the pink wig comes on, it’s getting bad.” ZO5 Christina Aguilera’s new purple-and-pink tresses debuted this week amid drama about her weight, with reports circulating that The Voice coach had once told her managers, “You are working with a fat girl. Know it now and get over it.” As it turns out, however, the comments (which had been attributed to a Billboard interview with Aguilera) were fabricated.

One Miley Cyrus up-skirt photo scandal too many, however, and Hilton is now an anti-bullying campaigner (with normal, non-evil hair). Kevin Winter / Getty Images
