Roger Federer and his wife, Mirka, are expecting their third child together next year. The father-to-be shared the happy news on Twitter this Christmas.
"Mirka and I are very happy to share the news that Myla and Charlene will be big sisters in 2014! Happy Holidays … " the 32-year-old tennis legend wrote.
Federer's wife also used to play tennis professionally, before retiring due to persistent injuries. They met at the 2000 Olympics, where both competed.
She's been a fixture at his matches for many years now, as he's won a record 17 Grand Slam singles titles in his peerless Hall of Fame career.
Roger and Mirka Federer, 35, tied the knot back in April 2009 and their identical twin daughters, Myla and Charlene, born later that year, are now four.
