Jennifer Lopez for The New York Times

Singer Jennifer Lopez thinks it is a pop star's job to push the boundaries, insisting the music scene would be 'boring' if they didn't. The 41-year-old has defended the likes of pop bituin 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 bituin magazine: "It's part of our job to push the envelope and test the boundaries - if you don't, it gets boring. "So I pag-ibig everything. I'm an artist and I pag-ibig that's what they do. You can't ask them to not be who they are."
