Lily Allen giggles as she heads out with husband David Harbour and daughters Ethel and Marnie on her 36th birthday

Lily Allen was in high spirits on Sunday when she stepped out in Manhattan with her two daughters Ethel and Marnie alongside her husband, Stranger Things star David Harbour.

Ringing in her 36th birthday in the Big Apple, Lily cut a stylish figure in jeans and a grey jumper, while David, 46, looked dapper in a navy bomber and Ethel, nine and Marnie, eight, wore padded jackets.

David appeared to crack a joke as the group made their way across the road, with Lily taking to Instagram upon their return to his New York apartment to document their celebrations.

The hitmaker revealed that her daughters had decorated their step-dad’s plush pad with Happy Birthday balloons and flowers.

Panning the camera over the table in David’s open-plan kitchen, Lily showed off flamingo-themed paper party plates, matching cups and a sprinkle-covered cake that read: ‘Happy birthday mummy, we love you.’

Lily and David’s new pet puppy Mary was also visible in the background.

The loved-up couple adopted the fluffy black pooch on Friday, and have since been sharing heart-melting snaps and videos of the dog on social media.

The actor and the British singer tied the knot in Las Vegas in September 2020 after a whirlwind romance at a kitschy wedding with an Elvis impersonator as the officiant. 

Lily told the Sex, Lies & DM Slides podcast: ‘We didn’t plan to announce it to anyone, it was meant to be a very private affair.

‘We were leaving Vegas and driving to Los Angeles and Nevada Clark County tweeted our marriage certificate.’

She quipped: ‘So that saying, ‘what happens in Vegas stays in Vegas’, what happens in Vegas gets tweeted out by Vegas!’
