So a camera crew in Croatia somehow wandered into 50's dressing room for an interview. Seems they were a little premature, cos there was some 'business' being conducted.
Reports on Croatian news are saying that Fif was filmed snorting a mysterious substance (well, I don't speak Croatian, but I think that's what they probably said).
I've checked and a) it's totally inconclusive as to what they're doing and b) it doesn't look like 50 himself is part of the party that is gathered around the table.
See what you think. It's about 1.30min in:
