In the most recent episode of 'My Little Old Boy', viewers were treated to a special appearance by actor Lee Jong Hyuk alongside his second son, Lee Joon Soo.

The nation first got a glimpse of Lee Jong Hyuk's sons on the hit reality show 'Dad! Where Are We Going?', where the kids embarked on adventures with their dads, capturing hearts with their adorable antics and heartwarming bonds.

Fast forward to 2025, high schooler Lee Joon Soo stands tall at a striking 194 cm with a shoe size of 300 mm. Shedding 21 kg to sculpt a slimmer frame from his previous 109 kg, he opens up about his personal life, revealing past relationships while maintaining close ties with his fellow reality show pals, particularly Yoon Hoo, son of singer Yoon Min Soo.

Lee Jong Hyuk shared a surprising story about sharing nine bottles of soju with his first son, Lee Tak Soo, who has since completed his military service. Known for his maturity on 'Dad! Where Are We Going?', Lee Tak Soo stands out with his poised demeanor, setting him apart from his younger sibling. Despite their contrasting personalities, both brothers share a common dream - to follow in their father's acting footsteps.
