I think it's a set-up. The fake "prossie" is wearing a wig, to disguise herself even further beyond the blurring. She's not used to it, which is why she's fiddling with it a lot.
The "agent" is confirming she'll text him once the girl is on her way - without even asking for the address. The part of the vid showing the "booking conversation" doesn't seem edited between start and finish, i.e. no bits left out. So, the girl had no way of knowing where to go unless she was in on it.
It's probably the female friend, who found the whole thing so hilarious. Hoiked up her boobs, and stuck a wig on.
