Liam posted an adorable photo of himself holding his precious bundle of joy, who at the moment still doesn't have a name. He wrote a heartfelt message in the caption about how happy he is to be a first time dad, along with how proud he is of his love Cheryl too.
"My close friends and family know there are very few times when I'm left speechless... wow! I'm incredibly happy to welcome our new baby boy into the world, it's a moment that I will never forget for the rest of my life and my favorite memory I have so far," Liam wrote.
"I'm completely in awe of his incredible mother and how she has been the whole way through this, she's really made my dreams come true. We haven't named him yet but he's already capturing hearts including mine. I feel very blessed. Happy Mother's Day everyone!" he added.
HOW SWEET IS THAT?! Cheryl took to her Instagram account too, sharing the same photo of Liam and their son, letting everyone know their baby made his big debut a few days ago on March 22, 2017.
"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 💙," she wrote.
Liam and his leading lady have stayed rather mum during Cheryl's entire pregnancy but after the couple appeared together at the Fayre of St James' Concert and she noticeably had a bump, it was pretty hard to deny the news that they were expecting. The former X Factor judge did flaunt her growing belly in a photoshoot she took part in for her charity work L'Oreal Paris UK, and Liam finally just recently opened up in an interview about the couple's growing family and how happy he is with Cheryl.
"She fully supports me. We're super happy. It's a very personal, precious time for us. I'm still learning. I'm only 23," he said.
It's clear Liam's son has already stolen his dad's heart! This little cutie is now the second 1D baby, as Liam's bandmate Louis Tomlinson welcomed his first son Freddie back in January of 2016. Hey, perhaps these two little guys would start up their own boy band one day. OK we're getting ahead of ourselves, but still, that would be perfect.
