Australian tennis champ Lleyton Hewitt and his wife, actress Bec Cartwright Hewitt, have welcomed a baby boy, named Cruz, born Dec. 11 in Sydney.
"All are doing well and are very excited about the new addition to the family," they write in the birth announcement on their Web site.
This is the couple's second child. Daughter Mia Rebecca was born in November 2005. The parents married in 2005, after having dated for eight weeks. David
and Victoria Beckham
also have a son named Cruz, age 3.
In June, when her pregnancy was announced
, Bec said of Mia, "She understands something's happening, and she's really excited about it … She'll be just over 3 when the baby arrives, and we think she'll be a good little helper."
Cruz's birth comes as his Wimbledon and U.S. Open champ father, 27, reportedly has resumed a rigorous training schedule following hip surgery – in a bid to return to the world's top 10 players.
