I assume she was only there because it was the birthday of her sister.
Her shacking up with a older dude, who was/is lover and ersatz-daddy at the same time, is wierd. But actually not that unusual as a rebel move.
But I'm not sure if that is still the current situation since she has already deleted any trace of him on her instagram.
Whatever, good luck young Gabrielle, see you in a few years when all those "I was forced to be on youtube" documetaries will be made and all these by then adults are going to spill the tea about how their parents sold their kids innocence for views-money and sponsored crap. /rant
