Jessica Simpson sang the National Anthem yesterday at the start of the Earl Woods Memorial Pro-Am in Bethesda, MD after which her boyfriend Tony Romo played a round of golf with Tiger Woods.  The one-day tournament was held at Congressional Country Club.

The Pro-Am was the kick off leading up to the 2009 AT&T National $6 million PGA Tour event that will be held during the 4th of July weekend in the nation’s capital.  Once again this year, tournament host Tiger Woods will pay tribute to the U.S. Military.

UPDATE:  The couple broke up a week after this event – see full story here.
