Those lesbian rumours must really have been getting to her, because Caoimhe has just proposed to her boyfriend from within the Big Brother house! The Irish housemate got down on one knee in the Diary Room and said to the camera: "Dave will you marry me in the BB house because I love you and think you're so beau?" She then told BB that she'd be happy to marry her man inside the house, as long as she gets a vintage gown and some champagne. "We think a BB wedding would be amazing," she gushed, adding that Josie would be her bridesmaid, Ben her Best Man and David could perform the ceremony. She is clearly crazy...but we like it! You'll have to tune in to Big Brother's Little Brother at 6pm tonight on E4 to witness Dave's response. He'll be going up against BB quitter Shabby in a game of Who Knows Caoimhe Best. Do you think he'll say yes?
