One Direction's Louis Tomlinson had the Internet melting when he shared a new father-son photo on Instagram Friday evening.

The black-and-white photo features a shirtless singer cradling his 4-week-old son Freddie Reign with one arm, while resting his other finger on his newborn's nose. "Lad and Dad," he captioned the moment.

Tomlinson and Los Angeles-based style Briana Jungwirth welcomed their first child together in Los Angeles on January 21. "I'm please to say my baby son was born yesterday :)," he tweeted. "He is healthy and pretty amazing :) I'm very happy!!"

A week following Freddie's arrival, Tomlinson doted over his baby boy by sharing a picture of his son resting on his chest. "Meet my little lad, Freddie," he wrote.

Meet my little lad, Freddie 👶
