The couple revealed the news with a joint Instagram announcement Friday, which they simply captioned, “️ 11•22•24 ️.”
The date was accompanied by a photo of the waterfront proposal, which featured a flower arch and an array of candles.
In the sunset shot, the Buffalo Bills quarterback, 28, could be seen on one knee, receiving a sweet smooch from the pop star, 27.
For the elaborate proposal, Steinfeld donned a floral shift dress and black heeled boots, while Allen sported a black long-sleeved shirt, khaki pants and white shoes.
“Congrats brother!!! ” Chad Michael Murray commented, while Serena Williams wrote, “ omg I love you .”
“Congratulations ,” Sara Sampaio remarked, while Tommy Dorfman exclaimed, “YESSSS.”
The actress and the NFL star were first linked in May 2023 when they were caught packing on the PDA during a sushi date in New York City.
An eyewitness told Page Six at the time that they were “canoodling” and “making out during dinner,” emphasizing that the outing “wasn’t platonic.”
The pair’s romance was confirmed that July when they were photographed getting handsy in a hot tub during a Mexican getaway.
Though the “Love Myself” singer and the athlete have tried to keep their relationship out of the spotlight, she’s been seen cheering him on from the stands during game days and spending time with his mother.
The duo didn’t go Instagram-official until this past July.
