The news comes after Mario finished in third place, leaving only Josie and David left in the house.
When Davina announced her name, Josie stood up with her hands on her head as David clapped her on.
The two then embraced and David told her that she was "amazing".
"Who do I think I am?" Josie laughed as Davina told her congratulations.
David said that he thought he had done "pretty well" and left the house to 'Living On A Prayer' by Bon Jovi.
He received mass cheers from the live audience and lapped up the attention with arms raised.
