The Voice host will play ‘a love interest who ruffles feathers’ in the series, joining recently-announced cast members Rachel Griffiths and local Lincoln Lewis.
McMullen, who has previously been producer and entertainment journalist, has a sole acting credit on IMDb playing a TV presenter on UK series The Magicians.
“Acting has always been a big passion of mine. For many years it had to take a back seat when my presenting roles took off around the world. I promised myself at the end of last year that I was going to focus more energy on pursuing interesting roles to sink my teeth into,” McMullen said.
“I’m excited to be able to play such a meaty role on House Husbands and to be able to work alongside such an esteemed cast in an award-winning drama. I can’t wait to show people another side to me.”
He is currently hosting observational series Darren McMullen’s Outsiders for National Geographic.
House Husbands returns later this year.
