Davina's in the house! For all of 10 minutes

Quote of the week from Davina McCall: "Four men mooing and oinking and neighing at me was weird. I never thought they'd be scared of a chicken."

Putting Davina into the Celebrity Big Brother house was a genius idea, but they didn't exploit its potential. True, the bit where she was laughing with Stephanie was great, but all that pointless running around the house while the bemused housemates, who'd already guessed she wasn't Nicola, looked on was just silly.

She should have revealed herself much sooner, and she should have stayed in the house much longer. Why leave as soon as she was unmasked, before even any conversation? Why not live there for a couple of days until the final?

Talking of which, who do you think's going to win? Alex is the hot favourite, much to my surprise, but then I had no idea Ulrika would win last year.

He has made a success of his time in the house, up to a point. He's shown that he is, on the whole, a nice bloke. But he's also proved he's rather stupid and gullible - all that stuff with Stephen Baldwin when he became his disciple was cringe-making, as was his adoration of Vinnie Jones. Plus he's been economical with the truth, going on about how manipulative the media is when he's sold stories and done his best to become famous.

So I rather hope he doesn't win. I'd like brilliantly snobby but very funny Stephanie or Dane - who's turned out to be intelligent and decent - to triumph, please.
