The odds of the Federer twins winning a Wimbledon doubles title in the future have dramatically shortened after Roger Federer and his wife Mirka announced the birth of a second set of twins .

The Swiss tennis ace revealed the amazing news on his Twitter account just hours after he announced he was pulling out of the Madrid Masters to be at the birth: "Mirka and I are so incredibly happy to share that Leo and Lenny were born this evening! #TwinsAgain#Miracle."

The two boys were born almost five years after the arrival of their twin sisters Myla Rose and Charlene Riva in July 2009 triggered a flurry of good-natured jokes about future doubles champions.
