Rapinoe is technically the youngest of five siblings, but her fraternal twin sister Rachael only beat her by minutes. The twins began playing football at age 4, and they went on to play at the University of Portland together. Both sisters also happen to be gay, which they learned after coming out to each other their sophomore year of college.
"It was just a matter of one of us saying it first," Rachael explained to the New York Times during an April 2013 interview. "That was really it. I had been dating someone and one of us said it first. It was a ripple effect. We both kind of came to the realisation that we're in this together." Now they run a joint business called Rapinoe FC, which sells apparel and offers football training clinics for kids nationwide.
