VIDEO : Picture This: Ed Sheeran May Have to Pay $20M For Ripping Off 'Photograph'

Ed Sheeran's "Photograph" topped music charts and his music video has been viewed on YouTube more than 200 million times. But the Grammy winner now faces a $20 million lawsuit, which claims his hit song has "striking similarities" to another song released by British singer Matt Cardle. CBS News correspondent Jamie Yuccas reports the two songwriters suing Sheeran say the 2014 mega-hit is a rip-off of their ballad, "Amazing," written for Cardel's 2011 album, "Letters." In order to prove their case, entertainment attorney Ken Abdo said the plaintiffs "have to show access - that there was some exposure of one song to another."
