Miroslava Vavrinec, who’s better known as Mirka Federer, is the wife of 20-time Grand Slam champion Roger Federer. She was actually a former tennis player who first met Roger when they attended the 2000 Olympic Games in Sydney. Two years later, she’d step away from the sport for good, citing a persistent foot injury.
While Mirka wasn’t exactly a top-ranking pro tennis player, she earned close to $300,000 in prize money throughout her entire career. She and Roger tied the knot in 2009, and in that same year, she gave birth to twin girls. Five years later, she gave birth to another set of twins—this time, boys.
