The 33-year-old, who has previously presented ‘The One Show’ shared the news on social media, revealing she’s keen for her baby to have ginger hair.
“So, I’ve been baking for six months now... and I’ve made a bun,” she captioned a shot of herself pointing to her belly on 16 November.
“It’s currently in the oven and will be ready by spring time. We are so, so thrilled (since I’ve taken my head out of the toilet bowl) and can’t wait to welcome a mad, wonderful little human into our world.
“Really hoping he/she is ginger.”
Scanlon, who wed Horgan in 2014, also comically shared the news on Twitter.
Posting a photo of an orangutan meme with the caption: “Get pregnant they said, you’ll glow they said”, Scanlon made the point that she definitely didn’t feel “glowing”.
“Apart from feeling severe resentment at the lack of promised ‘glow’ we are so, so delighted... plus, my hair looks great,” she tweeted.
Congrats to the couple!
