Big Brother presenter Brian Dowling has insisted he isn't worried about following in the footsteps of former host Davina McCall.
The star, who won the second series of the show and the Ultimate Big Brother in 2010, will present the new series which launches on Channel 5 with a celebrity version this week before the main show begins.
Brian said the new show would be very different from the one he originally won.
He said: "When I did the show 10 years ago this year I got on a train to Liverpool Street, got in a taxi and went to a Holiday Inn.
"It was so different. I walked into a field, there was two photographers, there was no crowd, there was no live show. It was a very different show and has completely evolved from a social experiment when I did it to when I did Ultimate Big Brother last year which was a massive thing.
"What I'm saying is it's now an entertainment show. It's not a social experiment, there's no barbed wire, no chickens. I hated the chickens. Its a primetime entertainment show."
Brian said the cast for the celebrity version, which has still to be announced, made his job easier because "people are going to want to watch".
The Irishman - who took over from Davina after she left the show when it was dropped by Channel 4 - said he was bound to be compared to his predecessor.
But he added: "I'm not a woman. I look up to Davina, I think she's super talented and she does live television flawlessly but we are very different."
The show also features Emma Willis who presented original spin-off show Big Brother's Little Brother. She will present the new version, called Big Brother's Bit On The Side.
