Susanna Reid and Piers Morgan among first to congratulate 'pregnant' Cheryl

After months of speculation, Cheryl finally showed off her baby bump for the very first time on Tuesday night, as she stepped out for a Christmas carol concert with boyfriend Liam Payne. Unsurprisingly, her as-yet-unconfirmed pregnancy was a hot topic the next morning on ITV breakfast show Good Morning Britain, with hosts Susanna Reid and Piers Morgan among the first to publicly congratulate the parents-to-be.

Commenting on snapshots of Cheryl and her bump, Piers said: "Congratulations Cheryl – but if you're watching this, you can't kid a kidder. You're pregnant, get on with announcing it. We are very happy for you."

Echoing her co-host, Susanna added: "Is it reasonable at this point to say, 'Are you pregnant?' There's no longer a food baby!", before Piers quipped: "I think we can get past the 'is she or isn't she'. She’s about to give birth!" Mum-of-three Susanna agreed, saying that she suspects 33-year-old Cheryl is around six months pregnant.

Cheryl and Liam Payne are yet to officially confirm her pregnancy

Cheryl and 23-year-old Liam are still yet to officially comment on the pregnancy rumours – but both have spoken about their desire to start a family. "I'd love kids. I'm obsessed with babies,” Cheryl told GQ magazine in August 2014, "Of course I've thought about baby names. A million times! I like Alfie for a little boy. I know that's what I was put on this earth to do. To be a mother."

For his part, One Direction star Liam, 23, has also said he would love to be a dad. Speaking to Magic Radio in August 2015, he said: "I wanna have kids when, you know, I have the time, but at the moment life's so busy, and I wouldn't want to commit to something like that when I haven't got the necessary time for it yet. That's my careful planning ahead!"
