We now know the identity of the mystery man who took Britney Spears out for a Valentine’s Day dinner and played golf with her over the weekend. He is … a very normal guy.His name is David. He works for a law firm — he’s not a lawyer– does “field research” … kind of a jack-of-all-trades. He’s definitely not a wealthy guy.David — who is 27 — is from Atlanta and does not seem to have significant roots in California. As for his relationship with Britney … we’re told they met through friends. The pics (above) were taken at the Sherwood Country Club where Britney lives. He’s a big golfer and he’s teaching her the moves. Britney has actually taken a liking to golf and is thinking about becoming a member of the country club.As for the Valentine’s Day date, it was pretty quick. They were in and out of the sushi joint in less than a half hour. The bill was $60. David tipped $13.As for whether they’re dating … no one is saying (her reps have been dodging the issue with us for days) but it sure seems that way.
