He's the same guy from the Lace & Leather performance from The Femme Fatale Tour DVD/BR. He's been following Britney to EVERY single show since he was like 12 as shown in the video (@1:45):
And yet she still looks uncomfortable in every picture from the FFT meet and greets
Well he probably spent like $50,000 just to follow her on the Femme Fatale tour with M&G and travel prices so thats like extensive and near stalking so its understandable that someone with social anxiety could be uncomfortable with that
Kinda weird though. And his username.
