Cheryl made it clear she would not be making an official announcement about being pregnant.
But she has delighted fans by sharing the news of her baby’s arrival.
Posting to Instagram, Chezza shared a lovely picture of Liam cradling a tiny bundle – their first child together.
Alongside the touching snap, she wrote: On Wednesday 22nd March Liam and I became parents to an incredibly beautiful, healthy baby boy, weighing 7lb 9 and looking like a dream.
“Although he still doesn’t have a name he is already stealing hearts.
“We are all madly in love and overwhelmingly happy with our little arrival.
“Happy Mother’s Day to all the mothers around the world.
“A day that now has a different meaning to me forever.”
Proud new dad Liam shared the same picture with his boy, with his own message.
He wrote: “My family and friends know there are few times when I am left speechless…wow.
“I’m incredibly happy to welcome our new baby boy into the world.
“I’m completely in awe of his incredible mother and how she has been the whole way through this, she has really made my dreams come true.
“We haven’t named him yet but he’s capturing hearts including mine. I feel very blessed.
“Happy Mother’s Day everyone!”
There will always be the cynics, but we think it’s a pretty nice touch that they both gave a shout out to mummies everywhere when they are in that special baby bubble.
