David Harbour And Lily Allen Make Their Romance Instagram Official With Sweet Photo

The "Stranger Things" star and the British musician have also been getting cozy lately in New York City.

It seems Hopper has finally found love.

David Harbour, who plays the beloved character Jim Hopper on “Stranger Things,” and British musician Lily Allen have taken the next step in their relationship by making it Instagram official.

Harbour on Monday posted a mirror selfie of himself and Allen in the parking lot of Disney’s Magic Kingdom in Florida. The two seemed to have gotten into the Halloween spirit, wearing costumes. Harbour was dressed as a Disneyesque prince, while Allen, whose face was turned away in the photo, sported a princess gown over jeans and sneakers.

“The prince, princess and the parking lot,” Harbour wrote in the caption. “That seven dwarves mine ride is the best one in the whole damn park. Go on, fight me. #magic #disney #rulebreakers.”

Harbour posted his sweet Instagram more than a week after the couple attended The Skin Cancer Foundation’s Champions for Change Gala at the Plaza Hotel in New York City.

They were also caught making out on the streets of New York City that same week.

Some fans were overjoyed to discover the relationship.

Allen posted an Instagram story about Harbour hosting “Saturday Night Live” earlier this month, per People. In a sketch parodying a SoulCycle class, the “Hellboy” star wore a sleeveless shirt. Allen shared photos of his zoomed-in biceps and wrote “Mine.”

Although their relationship currently appears as idyllic as a fairy tale, Harbour would do well not to cross Allen.

The “Smile” singer had no problem humiliating her brother Alfie Allen in her song “Alfie” in 2006, before he became famous playing Theon Grayjoy on “Game of Thrones.”
