It must be the mustache! Remember back in May of last year (May 18, 2006 to be exact), Britney had a little slip up and nearly dropped baby Sean Preston? AND do you remember who saved the day? Brit's security guard with the porn star stache! The guy saving (attempting to) Sean Preston was her security guard. Now whether Britney is romantically tied to him is still unclear, though from my personal opinion I highly doubt it. X17 is reporting his name to be John Sundahl, a successful real estate agent (remember that part)
Which brings me to my next point. Splash News is reporting the guy below to be another possible love interest of Britneys. The odd thing is... he has the same identity as the guy above! Splash is reporting his name to be John Sundahl as well. Apparently, This old fug got paid to pose for Splash's cameras, and even dished a little dirt saying 1. Britney helped him after his stay in the hospital (due to problems with his bowel, ew) and 2. That he has been dating Britney for over 2 MONTHS now. Not only is this 38-year-old a real estate developer, and not only a recovering alcoholic, but is an AA counselor as well. According to Sundahl, Britney was the one that asked HIM out (well... actually that part doesn't surprise me *cough K-fed cough*). Funny though, I'm pretty sure Britney said herself she didn't go to rehab for alcohol: "Till this day I don't think that it was alcohol or depression." Things aren't adding up.
Here's basically what I'm getting at. I really doubt Britney is dating either of these guys. One of them clearly looks like her security guard (who was once before), and the other looks like some old fart wanting his 3 minutes of fame. The weird part is that the agencies are confusing two completely different people. Who is the real John Sundahl? We may never know.
And let's keep it that way.
