Tyler Joseph's Grandpa Is Rocking Twenty One Pilots Merch and It's the Best

Celebrities, they're just like us. 

Remember when you were young and your grandparents would think the world of everything you did (sometimes to the point of embarrassment)? Well, rockstars have proud grandparents too. Just look at Tyler Joseph's grandpa.

The Twenty One Pilots singer posted the best photo on Instagram on Monday (September 16) of his grandfather rockin' a t-shit from the band's latest line of merch. 

“Fuz, my grandfather, went to the mall and got this,” Joseph wrote alongside the picture. “First of the new stuff I’d seen in person. Step thrøugh or step øff."

Despite his grandpa's stern look, we know he's proud of his grandson. How could he not be?

Check out the awesome post below.

Twenty One Pilots are gearing up to release their fifth studio album, Trench, on October 5 via Fueled by Ramen. The duo has given fans quite the taste of what to expect by sharing four offerings off the upcoming record ("Jumpsuit," "Nico and the Niners," "Levitate," and "My Blood").
