It's Official: Tiger Woods to Be a Dad!

Superstar golfer Tiger Woods and his wife, Elin Nordegren, announced today on his website that they are expecting their first child .

"As some of you know, today is my 31st birthday. I'll spend it quietly with family and friends, but Elin and I have more exciting news to share: We are expecting our first child together this summer. Obviously, we couldn't be happier and our families are thrilled. I have always wanted to be a dad. I just wish my father could be around to share the experience."

You may remember that Tiger's dad, Earl, died in the Spring from cancer.

Tiger will be starting 2007 PGA Tour season at the Buick Invitational in late January, but until then, he's sticking close to home to spend time with his family during this exciting time.
