Caoimhe Guilfoyle walks from Big Brother 11

Caoimhe Guilfoyle has walked out of the Big Brother 11 house.

Caoimhe, 22, was applauded by fellow housemates as she walked out, 42 days into the show.

Last night she asked Big Brother if she could leave, saying she wanted to get back to her boyfriend and family and that she was finding life tough in the house.

Cute Aussie John James Parton cried after she left.
