#3 Edge, Lita, and Matt Hardy's love triangle was turned into a WWE storyline
Edge and Matt Hardy's WWE feud was one of the most popular instances where the lines between fiction and reality were effectively blurred.
Matt Hardy had been in a real-life relationship with Lita since 1999. It was in 2005 when they split as Hardy realized that Lita was having an affair with Edge. WWE fans also became aware of the situation. As a result, Edge and Lita's onscreen pairing received a lot of backlash on WWE shows.
Somehow, this real-life love triangle transitioned into a kayfabe storyline soon after everyone became aware of what had happened. It was a classic move made by WWE to capitalize on the audience's strong reaction to the situation.
A few months later, their feud ended in a ladder match between Hardy and Edge. Edge was able to win the bout thanks to interference from Lita.
In an interview, Edge even said that he and Hardy used the backstage animosity between them to their advantage in the storyline. Over the years, all parties involved in the love triangle have managed to overcome their real-life differences as well.
