omfg obviously she's not hiding *face palm* he's her body guard, he's protecting her, we can't see everything that's going on. If Gaga really wanted to hide she would have done so, she is much smarter than ducking under Pete.
Guys, she's hiding because she's not wearing the blonde wig. When she wears the blonde wig she walks on the streets without hiding and when shes brunette she does not like to show her face
Is she scared? I think so...but Peter is here to protect our Lady from these fuckin' paparazzis!! When I see this, Im a little bit sad cause Gaga is like : "Help me, help me Peter, he wanna kick me!" :,-(
Sometimes the Fame isn't a good thing, it's poison!! I'm not ready for those flashing lights lol ;-)
