Davina McCall is bringing a birthing bag with her to the final of Big Brother 7.

The presenter, expecting her third child, is worried that she could give birth at the show's compound in Elstree and has been told to have everything she needs at her side.

"I'm having a home birth which means that, actually, I can give birth wherever I go," Davina told the Sunday Mirror. "If I've got the birthing bag with me, I could be giving birth in my dressing room."

McCall added that her pregnancy will not affect her ability to host the series.

"I get so excited when I'm presenting the show that adrenaline kind of carries me through," she explained. "It's after the show's finished I just feel the need to lie down for a minute."
