Popular Perth radio presenter Nathan Morris is going back into the Big Brother house.
The *Nova 93.7 *breakfast host, below right, who was on the second season of Big Brother in 2002, will join other popular previous housemates returning today as part of the Unwelcome Guests stunt.
Joining Morris will be Ryan "Fitzy" Fitzgerald, Peter Timbs (from the first Big Brother), Regina "Reggie" Bird (winner of the third Big Brother) and Trevor Butler, who won series four and walked away with $1 million.
Fitzgerald, who was fourth on Big Brother in 2004, outed himself on his Sydney radio show yesterday as one of the "trespassers" who will enter the house this week and mingle with the contestants.
"I'm going back in the house," Fitzgerald said.
"There's going to be uninvited guests going in to the house and housemates have to ignore them completely to win the task.
"They are not allowed to talk to me."
Fitzgerald says he will wake the guests this morning but is unsure what restrictions will be placed on what he can and cannot say to the housemates, who have been in captivity for 10 weeks.The grand final for this year's series is set to air on Wednesday, November 7 on Nine/WIN.
