Justine Henin at the 2012 French Open
Former world number one Justine Henin has given birth to her first child – a baby girl called Lalie.
The Belgian star, who quit the game in January 2011, said that she and her boyfriend Benoit Bertuzzo were delighted with the news.
"We were anticipating this so much, and now it has happened, this afternoon a little fairy arrived to illuminate our lives," she wrote on Facebook.
"She is called Lalie, she is in top form and we are really delighted!"
The seven-times Grand Slam champion has focused on her tennis academy and charity work since an elbow injury prompted her to retire for a second time.
Henin, who began her career in 1999 and won 43 titles, said the highlight had been winning gold at the 2004 Olympic Games.
Retiring for the first time in May 2008 after becoming disillusioned with the game, Henin became the first woman to quit the sport while ranked number one.
Her 2010 comeback was short-lived: after hurting her elbow at Wimbledon she missed the rest of the season and, although she returned in 2011, she could not practise without pain and quit soon after a disappointing showing at that year's Australian Open.
