#4 – Cher & Greg Allman
If Cher really could turn back time, then her relationship history may well be the one thing she would do differently. With her doomed relationship with Sonny Bono very much history, Cher hooked up with Greg Allman from The Allman Brothers Band. They married in 1975 but it was annulled 8 days later. The couple later reconciled and had a son Elijah Blue but again things turned sour.
