Also got to remember most are paid to promote and paid to be in photo shoots for 'cool brands' and those brands still need to arrange their campaigns.

So although it looks like they've just gone on holiday on their insta, the reason they can be there in the first place is because they receive money from brands to allow them to do that. This can therefore be displayed as work as they'll show bookings, invoices and letters from brands requiring them to be in the sun etc etc.
