Fox added that her worry was fuelled by the fact her husband had been "drinking all day."
Quickly after posting, Fox updated followers reassuring those concerned that her "newly single" husband had returned.
Nikki said that thanks to the investigative skills of everyone online, she had been able to find the hotel.
"He went out and lost his phone and only woke up to one furious newly single wife," she wrote to friends.
"I'm sorry for posting here but I was so beside myself not being able to reach him since yesterday afternoon."
Fox finished by joking her husband had a new place to live, "in Bali."
