Who could forget Taylor Swift's disgusted face when she saw BFF Selena Gomez and Justin Bieber exchanging friendly kisses backstage at the recent Billboard Music Awards. But that wasn't the only hint that Taylor is clearly not a fan of Justin, reports Galaxie Blog. The 23-year-old I Knew You Were Trouble singer reportedly refused to comment about Justin's Milestone Award win at last weekend's award ceremony.As reported by US Weekly, when asked what she thought about Justin's achievement, Taylor replied, "Can we have another question?" And in a separate interview with Access Hollywood, when questioned about what she and Selena were whispering to each other while Justin was accepting his award, all Taylor could say was, "Oh, you do not want to know! You do not want to open that can of worms. Especially tonight." Yikes!
