New mum: The Harry Potter star, who has been dating the American actress for over a decade, stepped out with their new arrival in New York City on Monday

New mum Erin wore a black T-shirt and light wash jeans with a green corduroy coat and bright orange boots.

She topped her casual look off with a pair of sunglasses and seemingly went makeup free for the walk, pulling her brunette hair back from her face.

The couple met while working together on Kill Your Darlings in 2012 and have been together for more than a decade.

Daniel opened to People about the first time he met Erin in 2020, saying: ‘It’ll be a hell of a story to tell our kids one day because of what our characters do with each other’ referring to a sex scene the couple has in the film.

He continued: ‘Our characters are meeting and flirting with each other, so there is this kind of sweet record of us just meeting for the first time and flirting.’

The outing comes after it was reported that Daniel was expecting his first child with girlfriend Erin.

A spokesperson for the Harry Potter star was said to have confirmed the happy news in March.

They said that the couple, who’ve been together for over a decade, are ‘absolutely thrilled’ to become parents.
