'He's healthy and pretty amazing, I'm very happy!' Louis Tomlinson broke his silence to confirm the arrival of his and former fling Briana Jungwirth's baby boy on Twitter on Saturday
Louis, 24, indicated he was relishing his new-found fatherhood as he added: 'Daddy daddy cool,' moments later.
And as if his happiness wasn't evident enough, he followed his latest comment up with three smiley faces which appeared as ':) :) :)', on his personal account.
While fellow One Direction band-member Harry Styles appeared to be congratulating his pop pal with a tweet which read: 'Flowers all round,' the other boys - Niall Horan and Liam Payne - are yet to congratulate Louis on his happy news on social media.

Just hours after news of the baby's birth was confirmed by a source to People, Louis was pictured indulging in a spot of sunglasses shopping with a female companion.
He looked pensive as he browsed the store's offerings and appeared to be wearing a hospital band on his left wrist.
The white plastic bracelet identified him as the father of Briana's son and it's believed he was at his ex's side during the birth as he was determined not to miss the newborn's first precious moments, TMZ reports.

Louis has recently relocated to Los Angeles so he can make the baby his priority, with the Doncaster-born superstar buying a separate property for Briana to live in with their child.
A friend of Louis told the MailOnline the former X Factor contestant is planning to be a hands-on dad and support his ex in any way he can.
The pal said: 'Although they're not romantically involved, Louis thinks Briana is a great woman and will be a fabulous mother. Louis has been helping Briana financially and is prepared to get stuck in with all the tasks that caring for a baby demands.'
News he was expecting his first child sent shockwaves through his young fanbase when it was confirmed back in July.
At the time, the pair had been spotted on a series of nightclub dates in Los Angeles.

 Price to pay: The 23-year-old LA -based fashion stylist was forced off Twitter after being bombarded with nasty comments, following the confirmation she was going to father the singer's first child
The MailOnline revealed exclusively last year how Louis's mother Johannah Deakin – who has seven children including Louis – met Californian stylist Briana Jungwirth after she discovered she was pregnant last summer.
At the time, Briana lived with her mother Tammi Clark and stepfather Brett Clark in Calabasas, California.
Deakin traveled with her husband, Dan, to California and both sets of parents attended an ob-gyn appointment - in which they all saw the ultrasound and heard the unborn's heartbeat for the first time - with the parents-to-be.

Since the news first broke, multiple sources have claimed the globally-renowned singer will be a 'hands-on dad' despite the fact he and Briana are no longer romantically involved with one another.
The pair were introduced through mutual friends early last year following Louis' split from his long-term girlfriend Eleanor Calder in March 2015.
'Louis is happy and very excited about becoming a dad and he thinks Briana will be an amazing mother. It was a surprise at first, but he and Briana are very, very close friends and this has brought them even closer,' a source told People at the time.

'They are both really happy and although they aren't in a relationship, their friendship is extremely strong and they are both really excited about the baby. It's early days and Briana and the baby's health are the most important things right now,' added the friend.
The pair were pictured on a night out at The Argyle in California in early May 2015 before another night of partying days later at Project L.A. in Los Angeles.
Louis and the pretty stylist, who is said to be 'a very private' person, were also seen leaving Snoop Dogg's CD release bash in West Hollywood a few days later holding hands in the back of their ride home.
Moving on: Louis is now dating American actress Danielle Campbell
The stylist decided to remove herself from the spotlight early on in the pregnancy after she was bombarded with social media abuse by Louis' fans.
Things have changed since the star discovered he was to become a father as he has struck up a romance with Danielle Campbell.
The singer has been spotted enjoying one-on-one time with the brunette beauty in recent weeks as he embraces his hiatus from One Direction.
Good timing: The former X Factor contestant will be able to invest a lot of time into getting to know his son as One Direction are currently on a hiatus for an undisclosed amount of time
