Usher May 18, 2011

Originally a teen pop star, Usher has since launched an acting career and after the release of his third studio album, 8701, become a confident, sultry R&B singer and performer. "OMG," his 9th number one hit in the US, made him the first artist in the 2010's to collect number one singles in three consecutive decades, and only the fourth artist of all-time to achieve the feat.
