'Stranger Things' Star David Harbour Has the Cutest Dates for NYC Red Carpet

David Harbour's daughters may have just crowned him the coolest dad on the block after their night out in New York City.

The 48-year-old Stranger Things actor stepped out in the Big Apple on Wednesday, May 3, for an advanced screening of Guardians of the Galaxy Vol. 3–and he might have just made his daughters the happiest girls in the world by bringing them along!

Harbour was pictured alongside his two stepdaughters, Ethel Mary, 11, and Marnie Rose, 10–Lily Allen's daughters from a previous marriage–as they posed for photos on the red carpet before the event. 

The actor's stepdaughters stood on either side of him as he put his arms around them while they posed for the photo-op. Ethel donned a black tank top with grey ripped jeans while Marnie opted for a black dress with a cream-colored knit cardigan sweater overtop. Harbour wore black denim pants with a zip-up black jacket overtop of a button-up.

Harbour and Allen were first linked together in 2019 and tied the knot one year later on Sept. 7 at the Graceland Wedding Chapel in Las Vegas. 

"In a wedding officiated by the king himself, the people’s princess wed her devoted, low born, but kind credit card holder in a beautiful ceremony lit by the ashen skies courtesy of a burning state miles away in the midst of a global pandemic," Harbour shared on Instagram two days later. "Refreshments were served at a small reception following."

Ethel and Marnie played a major role in convincing Harbour to marry Allen, as he divulged in an interview with Jimmy Kimmel in 2021. One day, the actor was riding bikes with the girls, "and the little one was riding along and she was going like, ‘David, Dad, David, Dad.’ Because the ‘d’ got her confused." He continued, “And the older one got very upset with that, which I understand, and was like, ‘He’s not our dad! He’s not our dad!’”

"And then the younger one was like, 'Well what is he? He's kind of our dad.' She's like, 'No he's not, he's our stepdad.' And she goes, 'What is he?' And she goes, 'He's just some guy in our lives!'" Turns out, that interaction is what pushed him to make it official with his wife. "I was like, 'I need to marry this woman,'" Harbour told Kimmel.

And now they're one big happy family, and Harbour is scoring some major "cool" stepdad points!
