Neil Patrick Harris shares his life and two children - twins Gideon and Harper (both 1) -- with fiance David Burtka, and in "A Very Harold & Kumar 3-D Christmas," they share something new together, as well - the big screen.

"We don't really act together, we just live together and we certainly exist together, like all the time, but acting... it was weird, because we just exist on a different level," Neil told Access Hollywood of David joining the "Harold & Kumar" franchise, as he promoted the film over the weekend.

And Neil had nothing but praise for David, who makes a cameo as himself (with a twist).

"I'm very proud of him and I think he came across very well in the movie," Neil, who once again plays a druggie, womanizer version of himself in the third installment in the buddy comedy, told Access.

"He's a funny guy," Neil added of David.

The latest "Harold & Kumar" installment is in theaters Friday and Neil recognizes that the franchise has added to his hip factor.

"The H & K stuff brought a kind of hip-ness quotient to how people perceived me, I think" he said. "It seemed like before then, I was doing more mainstream kind of all-American guy."
