The One Direction star took to Instagram to show everyone how much his darling bubba is growing!
1D fans were delighted by the snap, which showed the bub enjoying some family time with his aunt and Louisโ sister, Lottie.
No caption needed, the photo showed the two-month-old fast asleep, lying peacefully in a light denim shirt and covered up in blankets.

Lottie looks adoringly at her nephew.
Clearly parenthood suits the 24-year-old.
And the feeling is mutual for Freddieโs mum, Briana Jungwirth.
The celebrity stylist recently turned to Twitter, to reveal what it was like being a parent.
When asked what the best part about motherhood is, she tweeted, โEverything about it is so special. Creating a lifeโฆ thereโs nothing like it. When you see your babyโs eyes, youโll know.โ

Using the social media outlet, Briana addresses claims her child was fake, with some fans alleging theyโd used a baby doll in photos.
โThat is just cruel. I donโt usually speak out but Iโd like to know how would you feel as a new mother reading something like this. How dare anyone call my child fake.โ
โThatโs sick and morally wrong. I wonโt let anyone take away the happiness I have for my son. I know Louis wonโt either.โ
Despite the negative aspects of being in the limelight, the mum-of-one is taking it in her stride.
Revealing more insight into her life, the pretty blonde got candid behind why she and Louis chose Freddieโs name.
โLouis loved the name Freddie.. I picked Reign and it sounded perfect together!โ She quipped.
While thereโs no official word on how Louis and Briana split their time with their son and who has full custody, itโs clear they are both enamored by their bundle of joy.

In Louisโ eyes, Freddie Reign is kicking ALL the goals!
The musicianโs granddad Len spoke to ITV Calendar about how heโs handling the big responsibility.
โHeโs learning very quickly to be a dad. I mean, Louis wants to be a great dad and he is a great dad and he will be a better dad. But itโs all a new learning curve for him.
Adding, โI see him changing Freddie and feeding Freddie, like we all do and all have done.โ
โBut itโs a new phenomenon for Louis and heโs learning very quickly on his feet.โ
