Journalist and presenter Maia Dunphy is expecting her first child with comedian Johnny Vegas.

The 38-year-old host of RTÉ2 series What Women Want shared their news on Twitter by posting a snap of the scan and photoshopping a pint of Guinness into the picture.

Dunphy captioned the photo, “Well Johnny, at least we know he’s definitely yours.”

Johnny added: “No need for a DNA test then, or for Maia to splash out on expensive maternity gear, just borrow my jeans.”
