When: 1984

Age: 18

Janet Jackson and R&B crooner James DeBarge eloped in 1984 after dating for a brief period of time. The singer faced pressure from her parents when they caught wind of the rushed relationship. Jackson and DeBarge annulled their marriage less than a year after exchanging vows. Years later, in 2005, rumors circulated that the short-lived union produced a love child. Jackson vehemently denied the allegations.
