Debbie Reynolds/Eddie Fisher/Elizabeth Taylor

One of the early Hollywood cheatin' threesomes occurred when Eddie Fisher left Debbie Reynolds for Elizabeth Taylor in 1958. Taylor left Fisher for Richard Burton just six years later. But Carrie Fisher remembers her parents' affair, commenting, "This made marriage to my mother awkward, so he was gone within the week. If Mom and Dad were Jennifer and Brad, then Elizabeth Taylor was Angelina Jolie. I saw more of Dad on television than in real life." [Daily Mail]
