Selena Gomez's surprise stint plugging Kim Kardashian's SKIMS line ended as quickly as it started. Gomez posted an Instagram story raving about the product, then took it down hours later – right around the time she posted a shout out to her good friend Taylor Swift. It’s a coincidental timing, as people stared pointing it out. Gomez praised her friend Swift, who has been very supportive of Gomez and her new singles and said that she’s on her side for life. Swift has been embroiled in a very public feud with Kardashian and Kanye West for years. Swift spoke to Vogue about how awful dealing with the backlash against her was then. Seems like best friend Selena is with her in ‘thick n thin’ no matter what.
