Neil Patrick Harris' daughter wants a house for Christmas.

The 43-year-old actor has admitted he and his partner David Burtka were stunned when they read their children's Christmas list and discovered Harper, six, wanted to wake up on December 25 to find a ''life-sized doll house'' under her decorated tree.

Speaking on 'The Late Show' on Wednesday (14.12.16), he explained: ''I said, 'Harper, a life-sized dollhouse for you is just a house. You want me to get a house for you?' And she said, 'Yeah.' What is it with these giant gifts? 'Where do we put a life-sized dollhouse that's large enough for you as a person?' And she said, 'On the roof.' ''

And it's not just Harper who has an obsession with giant gifts, as her twin brother Gideon has requested a bounce house and a life-sized rocket ship.

He explained: ''That's what he's after. We live in the city, that's what I said to him. 'Where are we supposed to put a life-sized rocket?' It's gonna be a late night on the 24th.''

However, although the couple - who got married in 2014 - are going to do all they can to get gifts their children want, Neil isn't planning to get him a rocket that is ''life-sized.''

Neil's strict views on Christmas presents won't come as too much of a surprise to his twins - who were born via a surrogate mother - as he recently admitted that he is a lot more strict on the youngsters than his husband David.

He said: ''[I'm the] bad cop when it comes to disciplining the kids'' and [my parenting style is similar to a] camp counsellor rather than a maternal nurturer. With kids you need to be able to answer their questions in earnest and you need to try and get from the way they are asking the question to what they might actually be wanting to know. The more communicative they have become, the sweeter it's been for me.''
