Roger Federer's wife Mirka has given birth to twin girls.

Federer won a record 15th Grand Slam at Wimbledon recently, with his heavily-pregnant wife courtside for his 77-game epic with Andy Roddick.

And she gave birth to Charlene Riva and Myla Rose on Thursday night.

Federer told his official website: "This is the greatest day of our lives. Mirka, Myla and Charlene are all healthy and doing very well."
