Lily Allen celebrates David Harbor’s birthday with a sweet post locked up

Lily Allen celebrated her boyfriend David Harbor’s birthday in a running of the bulls with a homemade cake and bunting.

The 34-year-old British singer isolates herself with American actor Stranger Things, 45, and her two daughters.

The couple are believed to have been in a relationship since the summer of 2019.

Sharing a photo of his birthday celebrations on Friday, Allen simply wrote, “HBD.”

Harbor shared a longer message with her 5.7 million Instagram followers, joking that those who forgot her birthday were “heartless idiots.”

Her photo seemed to show Allen’s two daughters, Marnie and Ethel.

“To all the friends and admirers who came up yesterday with birthday wishes, thank you, so happy to have so many people out there tracking down my career to be sick and embarrassingly lazy,” he wrote.

“And to those who didn’t, you guys are heartless idiots.

“Very pleased that the supply lines still manage to ship dinosaur sticks. A birthday is not the same without a collection of extinct species on a lush green radioactive fluorescent ice formation.

“I feel like a quarantined child again, on the brink of an ice age of 10,000 years. Hello triceratops! Looking slim!

He also joked that famous baker Paul Hollywood should call Allen for “baking tips.”

Allen was previously married to builder Sam Cooper, with whom he shares his two daughters.

Harbor, who plays Jim Hopper in the hit Netflix sci-fi series, was previously in a relationship with actress Alison Sudol, Fantastic Beasts and Where to Find Them.
