When it comes to Roger Federer, always expect new records.

The already father of a pair of twins welcomed another set of babies into the world  on Tuesday after his wife Mirka gave birth to boys Leo and Lenny.

The Swiss star announced the news on Twitter. "Mirka and I are so incredibly happy to share that Leo and Lenny were born this evening!" he tweeted.

Federer and Mirka are  parents to twin girls Charlene Riva and Myla Rose, born in July 2009.

The 32-year-old revealed on Twitter on Christmas Eve that the Swiss sweethearts were expanding their family in 2014. But Federer would not reveal his wife's due date or whether the couple were expecting another set of twins.

He will now swap new balls for new diapers although he hopes to be back on court in the near future.
