Singer Jennifer Lopez thinks it is a pop star's job to push the boundaries, insisting the âm nhạc scene would be 'boring' if they didn't. The 41-year-old has defended the likes of pop ngôi sao Rihanna, who has recently caused controversy with her racy performances, saying artists like her have to take risks with their stage antics. The On The Floor hitmaker told British ngôi sao magazine: "It's part of our job to push the envelope and test the boundaries - if bạn don't, it gets boring. "So I tình yêu everything. I'm an artist and I tình yêu that's what they do. bạn can't ask them to not be who they are."
