The tennis star Roger Federer — widely considered to be one of the greatest players in the history of the sport — is expecting a baby with partner (and former tennis pro!) Miroslava ‘Mirka’ Vavrinec. The 27-year-old announced the “really awesome news” on his website earlier today. “Mirka is pregnant and we are so happy to be starting a family together,” Roger writes. “This is a dream come true for us.” He adds,

“We love children and we are looking forward to being parents for the first time. Mirka is feeling great and everything is going well.”

Mirka, 30, is due this summer. The couple have been together for close to nine years.
