Call it "four-love" in the second "set." Roger Federer and his wife Mirka are now the parents of four kids after she gave birth to their second pair of twins Tuesday!
The Swiss tennis legend, the sport's all-time record-holder in Grand Slam singles titles, welcomed a pair of boys to join sisters Myla Rose and Charlene Riva.
"Mirka and I are so incredibly happy to share that Leo and Lenny were born this evening! #TwinsAgain #Miracle," Federer tweeted to his fans Tuesday.
The athlete, 32, signaled the imminent arrival yesterday when he announced that he was withdrawing from this week's Madrid Open in Spain.
"I've decided to withdraw from Madrid to be with my wife Mirka during these next few exciting weeks for our family," read a message he posted on Facebook.
"I sincerely 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!"
Roger and Mirka, a former tennis pro whom he met in 2000 while both were competing in the Summer Olympics in Sydney, tied the knot on April 11, 2009.
