Tennis star Lleyton Hewitt and wife have baby girl

Australian tennis player Lleyton Hewitt and his wife Bec are celebrating the arrival of a baby girl in their family.

''Bec, Mia, Cruz and I welcomed a beautiful baby girl into our family last Tuesday. Mum and baby are great! Dad, big sister and brother elated,'' the New York Post quoted Hewitt as writing on the couple's blog.

The couple already has two children, Mia, 4, and Cruz, 1.

Family and friends, including Bec's mother, Michele Cartwright, and Hewitt's best man, Hayden Eckermann, kept the secret close to their chests before the official announcement.

The baby's name will be sent to subscribers to their blog via SMS next week, according to Hewitt.
