Chris O'Dowd and Dawn O'Porter have revealed some happy news during their ice bucket challenge - that they are expecting their first child.

Comedian Chris posted the video of his own ice bucket challenge, which involves pouring a bucket of icy water over your head to raise money for research into motor neurone disease, and went on to give his nominations for the next people to get dunked for charity.

He said: "I'd like to nominate Richard Ayoade, Graham Linehan and Baby O'Porter. So brave."

The video then panned to Dawn, who poured a small cup of ice over her prominent baby bump.

Chris later tweeted: "Here's my feckin ice bucket challenge. Spoiler Alert - I'm not alone!

"Thought we'd better mention it, before I got O'Busted."

Dawn had previously said that she was sick of being asked about when she planned to have kids: " I think it's a really natural question to ask and I totally understand why people do.

"But I get slightly shirty because Chris could do seven interviews on the trot and not get asked once about me or if we're going to have kids."
