Neil Patrick Harris is only just remembering moments from his wedding

Los Angeles - Neil Patrick Harris' wedding day is a "blur".

The 41-year-old actor, who is set to host the 2015 Oscars in Los Angeles on February 22, tied the knot with his long-time boyfriend, David Burtka, at a castle near Perugia in Italy on 6 September, but claims he can barely remember their special day.

The Gone Girl star said: "So many visuals were seared into my mind that it's only now I'm able to remember certain things."

Guess what? @DavidBurtka and I got married over the weekend. In Italy. Yup, we put the 'n' and 'd' in 'husband'. pic.twitter.com/R09ibF41rt

So happy to be married to @ActuallyNPH! A great day. One of my favorite parts of festivities was the Orange Boy. pic.twitter.com/X6XQv6OEvb

Neil, who has four-year-old twins Harper and Gideon with David, insists their relationship hasn't changed since they exchanged vows.

He added to Us Weekly magazine: "We've been together 10 years. He's still the same great guy."

The How I Met Your Mother star previously revealed on the Late Show With David Letterman that Sir Elton John gave a surprise performance at the wedding after being invited as a guest.

He said: "It was fun! We didn't want to have to do it just in a couple days and we wanted to do a destination wedding.

"Our first trip together was in Italy so that seemed fun. We knew a friend of a friend of a dude who had a castle. So we thought, 'OK, that's fun!' There were about 50 people ... Elton John sang a few songs, which was super cool. He's a friend and I didn't expect that. That was overwhelming."
