Surprise, surprise: Justin Bieber is not a fan of his ex-girlfriend Selena Gomez's new flame The Weeknd. Video filmed by TMZ over the weekend shows the 22-year-old singer leaving celebrity hotspot Delilah in West Hollywood and being asked by paparazzi if he listens to the R&B singer. "Hell nah," Bieber declares. "That s**t's wack!" The pop star's comments come less than two weeks after photos emerged of The Weeknd and Gomez kissing during a date night.
