She arrived November 18,2015 so her 90 days is coming up soon. The rest of the girls that have entered so far have only been on a monthly basis.
Maybe Danaya and Ilona will both leave at the same time leaving Adele all by her lonesome for a couple of days for a little privacy since there is no privacy amongst them when all 3 are in there together. They should cut it back to having only 2 girls. They always say Two is Company and Three is a Crowd.
