Federer and Swiss tennis player Mirka Federer (maiden name, Vavrinec) met like all great tennis couples do — on the court. Partnered to play together at the 2000 Sydney Olympics for their home country, the then-18-year-old Federer had a crush on Vavrinec, three years his senior, per Yahoo Sports. So how did the two go from doubles partners to the ultimate dream tennis couple?

Wrestler Ludwig Küng revealed how the two came together as the wrestlers and tennis players were housed together at the Sydney Olympics. "We knew that Roger was into Mirka and then we helped him a little," he said (via TennisNet). They locked the pair out the back door and told them to get to know each other a little. "From then on, they were a couple," he added. By the last day of the Olympics, the couple had shared their first kiss (via Express).

After the Olympics, Federer and Vavrinec would continue to play together in mixed doubles and to represent their county. Already dating, the two continued to have some of the sweetest on-court moments as they played against Lleyton Hewitt and Alicia Molik (via YouTube).

After she retired in 2002 due to persistent injuries, Mirka became Federer's manager (via Yahoo Sports). The two dated until marrying in 2009, before becoming parents to a set of twin girls — Charlene and Myla, aged 11 — and twin boys — Lenny and Leo, aged 7 (via Who).
