Not so much as desperation cause she was doing fine before that, that specific moment certainly gave her a boost that she capitalized instantly cause she's not stupid. Same reason why she literally bought a whole building which is where she currently has her Cafe and 2 apartments.
I forgot to mention that not even by being butt naked on stage the Kiss of Life girls will get anywhere, after their controversies they literally killed all their momentum and their fanbase peaked already. Natty and Belle are definitely the ones that will outlast the group, one due her solo act potential and the other with her works as producer, Belle is heavily involved in writing and producing.
