Babies on board: Neil Patrick Harris and his partner David Burtka carry their twins Harper Grace and Gideon Scott on a stroll near their home in Los Angeles
He plays womanising Barney Stinson in the hit sitcom How I Met Your Mother, but real life couldn't be more different for Neil Patrick Harris.
The actor is revelling in domestic bliss after he and his boyfriend David Burtka welcomed twins via surrogate three months ago.
The couple were spotted enjoying a serene family stroll near his home in Los Angeles with their babies Harper and Gideon strapped to their chests.
The 37-year-old actor and his long-term partner, who both kept the little ones wrapped up, joined by friends and their dogs.
Harris took to Twitter this week to share just how much his life has changed since becoming a father, posting a picture of a Red Bull mini-fridge filled with bottles of milk.
'This pic kind of sums up my life right now,' he wrote.
Last week he said the pair are growing up quickly, noting: 'The tots both started laughing. On the same day.
'I'm now obsessed with getting them to do it. Babies laughing is like opium.'

The fraternal twins were born on October 12 and now live with their famous fathers in their Hollywood Hills home.
For now, at least, it remains a mystery to the pair as to 'whose is whose' in the biological sense.
Speaking about the surrogacy process, Harris told People magazine last month: 'We found an egg donor anonymously through a hilarious process of looking at people's profiles and then an amazing surrogate who had helped same-sex couples before.
'And then we inserted two eggs, one with my sperm, one with David's sperm and they both took.'
Burtka, who quit acting last year to become a chef, added: 'When we first found out it was fraternal twins, we were thrilled.
'We don't know whose is whose, but it's amazing how different they are already. She is all girl and he is all boy,' he added, before Harris elaborated: 'She is more emotional and verbal. He sleeps and burps a lot.'
Harris is, of course, juggling work with fatherhood and recently welcomed Katy Perry to the set of his hit show.
She filmed a guest spot with him on an episode set to air in the U.S. on February 7.
