Hailee Steinfeld and Josh Allen were rooting blue!

In a new TikTok from Allen’s sister, Nicala Madden, the Buffalo Bills quarterback, 27, and actress, 27, were seen celebrating Nicala's sex reveal party for her new baby.

In the Sunday post, Nicala and Brayden Madden asked friends and family to guess whether their second child would be a boy or a girl. After several rounds of replies, Allen and Steinfeld introduced themselves to the future baby.

Allen sported a blue short-sleeved button-down, while Steinfeld didn’t seem to know which sex to channel in her look and wore a pink and blue striped shirt set.

“I’m the brother of the mother, and I think it's going to be a boy,” guessed Allen.

“I’m kinda feeling like it’s going to be a boy too," the Hawkeye star added.

Then, Allen threw up a couple of peace signs for the camera while Steinfeld smiled widely.

The video also features Allen’s parents, LaVonne and Joel; his younger brother, Jason; as well as the expecting parents and their eldest child, Kashtyn, 1 — whose first birthday was on Sunday. Allen’s younger sister, Makenna, was not seen in the TikTok clip.

As the video concluded, Nicala, Brayden and Kashtyn held a cluster of pink and blue balloons. When they dropped them, the pink balloons flew in the air while the blue balloons sunk to the ground—revealing that they are expecting another boy.

Steinfeld and Allen were first linked in May 2023. The couple made their first public appearance together in October at the NHL's Buffalo Sabres' season-opener against the New York Rangers.

In February, a source told PEOPLE that their relationship is "serious."

"They always planned to spend more time together after his season ended. Things have been going really well," the source said. "They’re both very family-oriented and driven, and they want to protect their relationship and keep it private. They’ve been on the same page with all of that."

"Hailee’s in a great place and would love to settle down if it’s with the right guy," the source told PEOPLE.
