Travis Kelce is showering his big brother with love on National Siblings Day.

The 34-year-old Kansas City Chiefs tight end compiled a series of adorable childhood clips to celebrate Jason Kelce in a TikTok video on Wednesday, April 10.

Backed by the song “Family” from Kygo and The Chainsmokers, the video began with a clip of the two as toddlers playing in Teenage Mutant Ninja Turtles onesies.

In another clip, the two tackled each other under the night sky. “Down 10 hut,” one of them is heard saying.

As the video progressed, Travis showcased clips of them growing older and dancing inside a locker room, riding a camel, showing off Halloween costumes, and swimming laps inside a pool.

Some of their more recent moments were shown as well, including a clip of the two hugging one another after the 2023 Super Bowl and a clip of Jason, 36, congratulating Travis after the Chiefs beat the Ravens, securing their spot in the 2024 Super Bowl (in which they came out victorious).

“Had to wish my guy who loves made up holidays more than anyone a HAPPY NATIONAL SIBLINGS DAY!! ❤️🫶🏻,” wrote Travis in the caption.

Jason Kelce Says He Still Won’t Root for Travis and the Chiefs Over the Eagles — Even in Retirement

During a conversation with PEOPLE in January, their mother, Donna Kelce, shared that Travis and Kelce are “each other’s biggest fan.”

“We’re very, very small. We’re tight-knit. We stay together and try to help each other as much as we can,” she said of their family.

When Jason announced his retirement from the NFL in March, Travis was overcome with emotion as his big brother spoke about their close bond.

“There is no chance I’d be here without the bond Travis and I share. It made me stronger, tougher, smarter and taught me the values of cooperation, loyalty, patience, and understanding,” said Jason during his retirement speech.

Travis later reflected on his brother’s decision to retire from the NFL in an episode of their New Heights podcast.

“You’ve always been a step ahead of me in this game. It’s always been like I had that flotation device right there,” he told Jason. “To have you out of it, man it feels empty. It definitely feels like… it’s complete.”
