Length Of Marriage: 9 days
Cher and Allman married in 1975, less than a week after her divorce from Sonny Bono became final. In reality, the couple had been together for months, and both Sonny and Cher had been dating other people for the final few years of their marriage. But nine days after Cher and Gregg's spontaneous nuptials in a Las Vegas hotel room, she filed for divorce.
Although this debacle is often cited as a classic short-lived celebrity marriage, it wasn't, really. Cher rescinded her divorce request, and she and Allman stayed together until 1979. The marriage yielded a son, Elijah Blue Allman, and an album, Two the Hard Way (by Allman and Woman), which is considered the worst thing either of them released in their musical careers.
