Make that a table for six! Swiss tennis pro Roger Federer and his wife, former tennis pro Mirka Vavrinec, welcomed their second set of twins on Tuesday, May 6.

The athlete took to his Twitter to announce that his daughters, twin sisters Myla Rose and Charlene Riva, now have twin brothers.

"Mirka and I are so incredibly happy to share that Leo and Lenny were born this evening," Federer tweeted, along with the hashtags "#TwinsAgain" and "#Miracle."

The anticipated arrival of his sons prompted the 32-year-old to withdraw from this week's Madrid Open just yesterday, May 5.

In a Facebook post, the pro and caring father announced: "I’ve decided to withdraw from Madrid to be with my wife Mirka during these next few exciting weeks for our family. I apologize to my fans and hope to be back in Madrid next year. I’ll be training near my home, and am excited to rejoin the Tour soon!"

Federer and Vavrinec met while competing in the Summer Olympics in Sydney in 2000 and married in 2009
