Essential Insights into Lamine Yamal’s Younger Sibling, Age 3

We’re a long way from knowing whether Lamine Yamal’s younger brother will follow in his footsteps on the pitch, but in the early years of his life, he is already becoming a star in his own right.

If Spain can complete the journey to a championship, the entire Yamal family could soon become household names.

Who is Lamine Yamal’s brother?

Yamal’s half-brother, Keyne, was born in late 2022 and has become part of Spain’s World Cup run. Frequently shown by the broadcast crew during the tournament, Keyne has been seen celebrating and waving when the camera has found him, and Spanish fans have rewarded him with loud cheers.

Keyne and Lamine share the same mother but not the same father. Despite only being half-brothers, the two have a strong bond.

Lamine told reporters after Spain’s World Cup win over Austria, “I’m moved when I see my little brother this happy, as well as seeing my mum and friends living the life they always dreamed of.”

According to The Athletic, Keyne — who has plenty of free time, being three years old — attends “practically all” of Barcelona’s games, as well as the 2025 Ballon d’Or ceremony to support his brother.

Lamine has leaned into his brother’s fame, featuring Keyne in social media photos and videos; their mother does the same.

Whether Keyne could join his brother as a soccer star is still a long way from becoming clear, but in the social media era, he is becoming a different type of star at an even younger age.

How old is Lamine Yamal’s brother?

Yamal’s brother, Keyne, is just three years old. He was born in September of 2022 and will turn four this year.

It might take a few years for Keyne to become as good at golf as his half-brother is at soccer.
