"It's one of those style trends, along with Hammer pants and fanny packs, that still haunts us from the '80s and '90s. But for some reason, Rihanna and Miley Cyrus are trying to being back the — gulp — rat tail. The singers, who are obviously conspiring to make the hideous hairstyle popular again, have both sported it recently. Rihanna, 25, revealed her rat tail, which is so thick that it could also be considered a mullet, in a series of pics she shared on Instagram . Meanwhile, Cyrus admitted in an interview with Kelly Osbourne on "E! Fashion Police" Tuesday that she'd worn the look the previous day with the help of a clip-on rat tail. The good news is that Rihanna changes her hair even more often than Miley, so it's not a question of if but when that long hair in the back will be trimmed. As for Cyrus, she made it clear during her chat with Osbourne that she's over her short locks. "I'm secretly tugging on it every night and taking Viviscal," she said, referring to a hair-growth vitamin supplement. "I'm not going to lie. But I'm going to rock it while I have it." As long as her hair remains short, though, we beg her not to let dad Billy Ray Cyrus talk her into rocking a full-fledged mullet!"
