Celebrity Love Triangles That Prove Three Really Is A Crowd

Gwen Stefani, Gavin Rossdale, and "The Nanny"

In a tale as old as time, Gwen Stefani was devastated to learn that her then-husband, Gavin Rossdale, was cheating on her with their children's nanny. Sadly, this wasn't the first time that Rossdale had cheated—after their wedding in 2002, Rossdale learned that he was the biological father of his goddaughter, and Courtney Love later stated that she and Rossdale had an affair. "It was the beginning of hell. My dreams were shattered. All I wanted my whole life was to have babies, be married, like what my parents have," Stefani said.
