"It is 10 years since I won Big Brother so what better way to celebrate and mark that anniversary than to be asked to host the new series.
"It's on a new channel and a fresh start for the show that has kept the nation entertained for 11 years and I am so excited to be a part of it!"
Channel 5's director of programmes, Jeff Ford, revealed that he was "delighted" with the show's two new faces:
"As the Ultimate Big Brother housemate, Brian is the perfect man to be at the helm of Big Brother's new incarnation.
"Emma meanwhile is a consummate professional - as well as being a self-confessed superfan.
"Their combined expertise and first-hand experience of the show will bring an extra dimension to Big Brother when it returns this summer."
Celebrity Big Brother will start on Channel 5 this August, with the regular version following in September.
