After his name was called to accept his MVP honor at the event, Allen turned to Steinfeld for a kiss before walking onstage to accept the trophy.
"You've been my rock, you're my best friend. I would not be standing on the stage if it weren't for you," Allen said in a tribute to Steinfeld during his speech.
Steinfeld and Allen were first linked in May 2023. They then went Instagram official over a year later in July 2024.
Months later, Allen popped the question to Steinfeld in November, and the two announced their engagement in a joint Instagram post, in which they shared a romantic photo of Allen down on one knee in front of Steinfeld, with both surrounded by an arch of pink and red roses next to a body of water.
After Allen and the Bills were eliminated from Super Bowl contention last month, Steinfeld spoke with E! News about how proud she was of her fiancé's 2024-2025 NFL season.
"To say the least, I am so proud of that man," Steinfeld said, adding, "Everything he's done and everything that the team has done together, he is the hardest working person I know."
