Travis Kelce is converting his friends and family into Swifties one by one.

The NFL star, 34, attended girlfriend Taylor Swift’s Eras Tour in Sydney on Friday alongside his best friend Ross Travis — and the show surely made quite the impression on the latter.

Following the nearly four-hour event, Travis — who was spotted singing along in the VIP tent — took to his Instagram Story to praise the pop star, 34.

“I understand now…” Kelce’s friend wrote atop a photo of his outfit. “That. Was. Amazing.”

Travis — who has become quite close to Swift amid her romance with Kelce — seemingly had the time of his life at the concert, from dancing with fans to getting buddy-buddy with Taylor’s dad, Scott Swift.

Swift pulled out all the stops during the first night in Sydney, once again changing the “Karma” lyrics to honor her beau and making several sweet nods to the hunky athlete.

The 31-year-old also posted a video of himself doing Swift’s signature heart hand pose while she sang “Shake It Off.”

Like Kelce, Travis’ arms were covered in friendship bracelets after exchanging dozens with fans before and during the show.

“First show and made some friends tonight!” he wrote atop a separate image of all the bracelets. “Sydney… you didn’t disappoint! ❤️”

Travis and Kelce, who met while they both played for the Kansas City Chiefs, seemingly coordinated their colorful concert outfits — with the former wearing an orange-and-yellow crocheted set and the latter opting for a patterned blue ensemble.

The duo’s eye-catching outfits quickly went viral on social media as fans compared them to the yellow and blue M&M men.

However, Travis — who bears a strong resemblance to Kelce — took the joke in stride, posting a photo of the meme to his Story.

“Internet: 1 M&Ms: 0,” he wrote, adding two laughing emojis.

Although Travis might not have been a fan of Swift’s music up until now, he and the singer have become good friends and often sat together at Kelce’s football games.

Earlier this month, the pair were seen celebrating the Chiefs’ big Super Bowl win together, with Travis rushing to hug the “Anti-Hero” singer just moments after the game-winning catch.

Travis also posted several photos from inside their star-studded suite to his social media, including one photo of him and Swift holding up three fingers in honor of the three-time Super Bowl champion.

Now that Kelce’s season is over, he reportedly plans on spending a lot of time on the road with Swift.

The hunky NFL star touched down in Australia on Thursday and eventually reunited with his leading lady at her $25,000-per-night hotel.
