It's been a year when Big Brother has thrown absolutely all they've got at the contestants, and now one of them has finally walked, and we don't really blame him.

Former Big Brother winner Brian Belo joined the housemates almost two weeks ago as part of the Timebomb theme they are doing this year, and after threatening to leave for the last week, he has finally walked today.

Brian had clashed with fellow housemates Helen and Marc last week saying they were bullying Chloe, and fans have lashed out at former winner Helen on Twitter, blaming her for his departure.

However, it's not yet clear why exactly Brian has left but all will be revealed in tonight's show on TV3 at 10pm.
