(CNN) -- Triple grand slam winner Lindsay Davenport has pulled out of next month's Australian Open because she is pregnant with her second child.

Davenport will now take an indefinite break from tennis after revealing she is pregnant again.
The 32-year-old former world number one has confirmed she will now take an indefinite break from the WTA Tour.
"Of course this unexpected but exciting surprise now means I will be putting tennis on hold for the foreseeable future," Davenport said in a statement on Wednesday.
The American returned to the women's tour in 2008 after giving birth to her first child, Jagger, and has since won four titles.
Although Davenport has not played since the U.S. Open, fuelling speculation she was ready to retire, she entered the Australian Open last week.
The Californian has won 55 career titles and finished 1998, 2001, 2004, and 2005 as the world's top-ranked player. She is married to former All-American tennis player Jon Leach.
The Australian Open, the first grand slam tournament of 2009, begins on January 19 in Melbourne.
