Gary posted a family photo on Father's Day, showing off his wife, Dawn, daughter Daisy, 15, and Daniel, 24.
Barlow also shares daughter Emily, 22, with Dawn.
The photo shows 6'2 Daniel towering over his "short king" 5'7 father.
"Father's Day is the one day I think I'm allowed to post pictures of the fam hey???" Gary captioned the post.
Fans got very creative with memes, exaggerating how tall Daniel was.

A video of the father-son duo working out together has resurfaced following the viral photo.
"There's nothing I love more than spending time with my kids. Here's a little video of Dan and me having a father-and-son training session. I'm very proud of my boy and his commitment to his fitness," the caption read.
"Don't look at the difference in weights. Don't notice that I'm stood a little further forward to make the size gap smaller. Lol."
