But why does Louis keep going back to the Mayfair Hotel, when he knows that she knows he'll be there?

Last night, the fan was wearing exactly the same outfit as last time (now it's been in contact with Louis you know she's never going to wash it ever again) but had a different pair of boots on for him to sign.

Mickey Graham from Boyzone was also with Louis, keeping his distance and looking concerned. And wearing a hat just because he likes them, not because he's going bald or anything...

We sense a restraining being ordered...
