John Sundahl, a real estate investor and fellow AAer, is that mystery guy running around with Britney Spears over the holiday.

He’s said to be her bodyguard, but the two have kept very close company in recent days, fuelling speculation there might be more to it. The pair were spotted out and about in LA, where they shared an intimate dinner at the Four Seasons and later set off to watch the musical Wicked before returning to the hotel together.

Sundahl denied being romantically involved with her a few weeks ago, but either she’s hired him as a chauffeur/bodyguard/dinner companion, or they’re getting cozy again. C’mon, the guy went to see Wicked! He’s definitely into her.

Here’s more:

John Sundahl claims he and the Toxic singer are an item after meeting at an Alcoholics Anonymous meeting in Los Angeles. Sundahl tells the National Enquirer he knows Spears is serious about the romance because she recently helped him recover from bowel surgery. He says, "When I was in the hospital, she sat with me and held my hand all night long. She even sang and hummed to me while I was practically unconscious. "I love being around her. She’s a sweet, caring girl and a good mom." Sundahl claims Spears sought him out for counseling sessions after leaving rehab at Promises in Malibu earlier this year (07), and then started attending AA meetings he staged. The wealthy 38-year-old admits his romance with Spears could scupper part of her estranged husband Kevin Federline’s divorce battle - because the dancer/rapper’s legal team initially subpoenaed Sundahl to testify against the pop star.

Sounds like the Spears-Federline divorce is going to court.
