Just when Louis Walsh thought it was safe to venture outside again, his terrifying stalker No.1 fan was there (because she's everywhere, Louis) to greet him and ask for his 2998th autograph to add to her shrine collection...

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...
