Louis Tomlinson has expressed his joy after becoming a father for the first time, revealing his newborn son is "healthy and pretty amazing".
The singer shared his excitement with followers on Twitter, confirming his little boy was born on Friday.
"I'm pleased to say my baby son was born yesterday... He is healthy and pretty amazing... I'm very happy!" Louis wrote in a post on Saturday morning. He then added, "Daddy, daddy cool" along with smiley face emojis.
Reports suggest Louis' ex-girlfriend Briana Jungwirth went into labour late on Thursday evening, and the singer was by her side as they welcomed their son on Friday. He was later spotted shopping at a branch of retail outlet Sunglasses Hut in Beverly Hills, California while sporting a hospital band on his wrist.
Louis' One Direction bandmates are yet to comment on the news, but Harry Styles sent a cryptic tweet on Friday, writing, "Flowers all round."
A post from an account in the name of Briana's grandmother, Marianna Case, on Thursday read: "Louis just let your heart dance. You now have another you. A gift that will want to be just like you.
"Love him and my young grandchild that gave him to you. Let her know she's special. She just wanted to love you not even knowing who you were or your profile and reputation. Be free and just live. It's simple. Not complex."
The 24-year-old singer's stepfather Mark Tomlinson also seemed to confirm the news on Twitter on Friday, posting, "Is that the patter of tiny feet?"
