Australian tennis star Lleyton Hewitt may have lost to Roger Federer at Wimbledon, but off the court, he’s just hit another ace …

… if you know what we mean!

We mean he got his wife pregnant a second time. Game, set, match, mate!!

Hewitt, 27, has announced that he and his wife, Bec Hewitt, 24, a former soap opera star, are expecting their second child in January.

“It’s fantastic,” Lleyton Hewitt told Australia’s edition of celeb gossip mainstay OK! Magazine about the celebrity baby news.

Lleyton and Bec Hewitt married in 2005 and had a daughter in 2006.

The impending, athletic celebrity baby will join big sister Mia Rebecca, 2, who is already thrilled about becoming an older sister.

“She understands something’s happening, and she’s really excited about it,” said Bec Hewitt of her first baby.

After dating for only eight weeks, Bec and Lleyton Hewitt became engaged and then wed the following month. Congrats on that too, kids!
