Ed said in November having Lyra Antarctica was a "blessing" and "miracle" after he and Cherry struggled to conceive "for a while".
They had their eldest daughter last August after a natural conception while they were on holiday in Antarctica, which inspired the girl's name.
And it would seem Sheeran's wife became pregnant again almost immediately given the singer told fans in May he and his wife had a second daughter, saying he was "over the moon" to again be a dad.
He announced the news by sharing an image of a white pair of baby booties on Instagram, saying: "Want to let you all know we've had another beautiful baby girl. We are both so in love with her, and over the moon to be a family of 4 x."
Ed has also said he wants to add more kids to his brood, telling the Open House podcast in June: "I would obviously be super grateful to be able to have any more kids, but I think girls are far superior to boys. As a boy myself, I feel like I can say this.
"I feel like we were so lucky to be able to have one that I think I would obviously love more. But I think we're so lucky to just have one. So if nothing else happens, I'm so happy, basically."
