Edit the phone number out for the poor bastard, he's too smitten to realise what he's done
I suppose it could be true, given that she hasn't been photographed for a while. If so, you're lucky. Just keep in mind that she probably likes her boyfriend more than she likes you :P
It doesn't sound like he's trying to show off, he's just trying to work out whether he saw what he thinks he saw. Or who he saw, I suppose.
For all we know it's to be the set of a new movie or something. I mean, plenty of people may have seen her walking around Prague when she was shooting Zhivago. She's just more well-known now.
