Louis Tomlinson has introduced his son Freddie to the world with - what else - a picture on Twitter.

It's been a big week for the 24-year-old One Direction star, who welcomed hisĀ child withĀ Briana Jungwirth on Saturday. Not only has he had all the elation and stress of becoming a first-time dad,Ā he's also faced the ire of some fans who refuseĀ to believeĀ his sonĀ had made an appearance.

Now that they've witnessed Louis and Freddie, One Directioners have goneĀ into meltdown.Ā In a matter of hours, the post had racked up more than 327,000 likes and 235,000 retweets.
