HER husband Chris O'Dowd is fast becoming the hottest ticket in Tinseltown and Broadway.
And, according to Dawn O'Porter, the secret to Chris's success is that he never knows when to keep his mouth shut.
"Chris has no editor in his brain," Dawn told the Diary.
"He says what he thinks. But I think that's what's really good about him and I think people like that. He's very honest and funny, he's just having a laugh.
"In Hollywood, people can be very media managed, but he just goes on these chat shows like Letterman and is utterly ridiculous. And I think that's really entertaining."
Dawn and Chris spilt their time between London and LA.
"We live in London, but Chris is in Ireland for the summer with Moone Boy and then we're in LA for winter," said Dawn.
This summer, the couple bought a house in the Hollywood Hills. They flew over to LA at the beginning of this month with their beloved pets Potato the dog and Lilu the cat.
Despite having A-Listers for neighbours, Dawn admits there are still some celebrities who intimidate her.
"They are the two that would have me hyperventilating," she said. It's going to be a busy few months for the pair.
While he gets ready to tread the boards, Dawn is busy researching her new Channel 4's show This Old Thing.
The six-part TV series is all about secondhand swag; which makes sense given Dawn's love of retro gems.
Dawn will be joined on screen by her pal, the celebs favourite vintage supplier William Banks-Blaney -- who helped Dawn find her pale blue wedding dress.
And the style maven is writing a thick coffee table book to accompany the series.
"I feel very lucky to write about the thing I love more than anything else," she said. "We had so much material for the TV show, so it's fantastic to have another outlet to build on the series. I still can't believe it's happening!"
In the TV series, Guernsey native Dawn will take vintage virgins and introduce them to the thrifty world of secondhand fashion. She's also working on the follow-up novels to her book Paper Aeroplanes about school pals Flo and Renee.
