Travis Kelce in celebratory mode over Josh Allen, Hailee Steinfeld engagement

Travis Kelce is celebrating Josh Allen's romance with Hailee Steinfeld.

The Kansas City Chiefs star, 35, left warm greetings for the newly engaged couple under their announcement post that came Friday.

“Congratulations!!!" wrote Kelce in the comments that instantly filled up with congratulatory messages from friends and fans, all in awe seeing the photo of the Buffalo Bills quarterback, 28, proposing to the actress, 27.

Allen’s team also responded, exclaiming, “LET’S GOOOOOO!!," while the official NFL Instagram page also anticipated the new beginning, commenting "Congrats" with a hearty hand emoji.

Jacksonville Jaguars’ Gab Davis also commented, “Yes sirrrr [heart emojis] congrats," as former Bills and Philadelphia Eagles player LeSean McCoy said, “Congrats franchise."

Bills defensive end Javon Solomon, meanwhile, replied with a victory and heart emoji.

Allen and Kelce both starred in Pepsi’s "Make Your Gameday Epic" campaign ahead of the 2024-2025 NFL season earlier this year, alongside Derrick Henry and Justin Jefferson.

They have been friends who have traded friendly jabs over the years—especially when it comes to their respective relationships.

Allen proposed to Steinfeld on November 22. A source close to the couple told People Magazine that their families are excited about the engagement news. "They’ve been head over heels from the start," the insider told the publication.

Steinfeld and Allen were first linked in May 2023, and the couple then made their first public appearance together at an NHL game at the KeyBank Center in Buffalo in October 2023.
