The 32 year old announced he and his model wife Elin Nordegren will welcome their new addition in "late winter" on his official website last month (Sep08).

But Woods admits he's been tempted to find out whether his one-year-old daughter Sam can expect a baby sister or brother before the new year.

When asked if the couple knows the baby's gender Woods says, "We don't. We have that envelope (and) they gave us the photo."

But the guessing game isn't new to the couple, who wed in 2004. Woods adds, "We didn't know the first time."
