GRETEL Killeen has been dumped from Big Brother as Channel 10 seeks to revamp the struggling show by introducing new hosts, Kyle Sandilands and Jackie O.
``Working on Big Brother has been an extraordinary, challenging and rewarding experience,'' Killeen said.
``I'm really proud of what we've achieved, but I now have the seven-year itch and am busting to get on with a million new things, including my first feature film which we're shooting in the new year.''
After seven years, the show is in much need of a change.
The 2007 series was criticised for its boring and predictable housemates, resulting in poor ratings and speculation the show might be axed.
But producers Endemol Southern Star have confirmed the show will return next year with a ``tighter, re-energised format''.
Jackie O said: ``It actually gets really boring after a while. As a fan, I have always wanted a bigger variety of people in there and also to push the contestants more.''
Jackie, 32, also revealed she was desperately trying to have a baby.
``I'm clucky ... my husband and I are both ready for it,'' she said.
Sandilands was a contestant in '02's Celebrity Big Brother and was a guest in the house for a weekend this year, although he had to leave early with a migraine.
``I want that conflict, that real sense of drama rather than that frat-house drama that we've seen over the last few years,'' said Sandilands, who is also a judge on Ten's Australian Idol.
``It is time that we mix it up a little bit. We will still have young fun people in there, but the whole house won't be full of 20-something losers. I would like the old grumpy man that hates loud noise and hates young people in there.''
