The same mystery man who dined with Britney Spears on Valentine's Day took her out golfing this past weekend, and now we know he's just a regular dude named David .

According to TMZ , David is a 27-year-old who lives in Atlanta, and works as a "jack-of-all-trades" and field researcher for a law firm.  He was reportedly introduced to Britney by friends.  While he may be of modest means, David is a pretty generous tipper.  According to TMZ, during the Valentine's Day dinner, David tipped $13 on the couple's $60 bill at a sushi restaurant: slightly more than 20 percent.

Since her split from ex-fiance Jason Trawick , Britney and David have also been spending time together on the links, according to TMZ.   Apparently, David's an avid golfer, and now Britney has taken a liking to the game.  This past weekend, the two were spotted together playing golf at the Sherwood Country Club near her California home, and TMZ reports that Britney is now considering becoming a member of the club.
