Robert Sylvester Kelly (born January 8, 1967 in Chicago, Illinois), better known by his stage name R. Kelly, is a Grammy award winning American R&B singer-songwriter, rapper, actor and record producer. Debuting in 1991 with the group Public Announcement, Kelly went solo in 1993, starting off a successful career with the release of the album 12 Play. He has since released a further eight studio albums, collaborated with Jay-Z on two albums and has had many successful singles including Bump N' Grind, I Believe I Can Fly, Ignition, The World's Greatest and the hip-hopera Trapped in the Closet. His ninth studio album, Zodiac, will be released sometime in 2010.

Kelly has also produced and performed in many tracks by other R&B and hip-hop artists. In 1994, Kelly produced and wrote the debut album of R&B singer Aaliyah and in 1995, Kelly co-produced and wrote the song "You Are Not Alone" for Michael Jackson, which was included on Jackson's album, HIStory. Kelly has sung the hooks for many notable hip-hop songs, such as "Fuckin' You Tonight" by The Notorious B.I.G., "We Thuggin'" by Fat Joe, "Gigolo" by Nick Cannon, and "Go Getta" by Young Jeezy, and has collaborated for two albums with Jay-Z.

In his personal life, Kelly has had several sex scandals. Reports surfaced that he married the then-teenaged Aaliyah, for whom he was a songwriter. Kelly and Aaliyah annulled their marriage. After a video of a man purported to be him having sex with an underage girl was released, Kelly was indicted on several counts of child pornography in 2002. After several delays, his case went to trial in 2008, with the jury ruling Kelly not guilty on all 14 counts.
