( CNN ) -- Rock ' n ' roll legend Jerry Lee Lewis is married for a seventh time -- this time to the ex-wife of a cousin whose sister Lewis wed when she was 13 -- his representative said Thursday . Lewis , 76 , married Judith Brown , who was previously married to his cousin , Rusty , on March 9 in Natchez , Mississippi , according to his representative Maureen O'Connor . The flamboyant piano player known as `` The Killer '' pushed the rock envelope with his 1957 hit singles `` Whole Lotta Shakin ' Goin ' On '' and `` Great Balls of Fire , '' but marital scandal stalled his career . His third marriage ( when he was 23 ) was to a 13-year-old cousin , Myra Gale Brown . Rusty Brown is Myra Gale Brown 's brother , O'Connor said . Lewis and his sixth wife , Kerrie McCarver , were married for 20 years and had a child . They were divorced in 2004 , according to Spinner.com . CNN 's Denise Quan contributed to this report .
