The 38-year-old actor and his wife Jenny Mollen announced they were expecting another child together on Wednesday (05.04.17) but didn't share the happy news in the most conventional way as they enlisted the help of a baby nasal aspirator.

The couple shared a photo on the blonde beauty's Instagram account which showed the pair of them snuggled up in bed together with one end of the NoseFrida sucker - a product they're seemingly plugging - up his nose and the other end in her mouth.

The 37-year-old actress joked in the caption that they had told their three-year-old son Sid that they'd created his unborn sibling using the nasal aspirator.

She wrote: "This is how I told my son babies are made. #numbertwo #nosefrida @fridababy #teetsreincarnated (sic)."

Jason then shared the same photograph on his own social networking sites.

It's not yet known how far along Jenny is or whether they know the sex of their child but last October she joked that pregnant women should take photographs of their boobs before they hit the second trimester because they never shrink back.

She said at the time: "Whenever I see a pregnant woman, the one thing I wanna stop her and tell her is to take as many pictures of your boobs now, because they're never, ever going to look this good, ever again."

Jason and Jenny worked together on the set of 'My Best Friend's Girl' in 2008 with Dane Cook, Kate Hudson, Diora Baird, Lizzy Caplan and Alec Baldwin.

The pair ended up getting engaged in January of the year the film came out on went on to tie the knot in April in a small, intimate, ceremony in Los Angeles, California.
