TV3's Seven O'Clock Show host Lucy Kennedy has announced that she and husband Richard Governey are expecting their third child.

The Seven O'Clock Show posted a video on Twitter early on Wednesday showing a bun in an oven, and Kennedy confirmed her happy news live on air that evening. 

"We are absolutely thrilled and very excited to announce that baby number three is in my tummy," she said.

The presenter said her children Jack, aged six, and Holly, aged four, are very excited and have offered their toys as presents for the new arrival. 

"We're due around Christmas Eve, please God," Kennedy added. "We can't wait."

The show's producers said they would be looking for "big names" to stand in for Kennedy with co-host Martin King while she is on maternity leave.
