Neil Patrick Harris and Jayma Mays Got Smurfed Up in Vegas

What happens in Vegas stays in Vegas, unless someone named Neil Patrick Harris tattles on you.

Somewhere out there, some three-apple tall blue guys are surely very unhappy with the one and only NPH and his "The Smurfs 2" co-star Jayma Mays for spilling on their Smurf shenanigans (Smurfnanigans?) to NextMovie at the Paris Hotel and Casino in Las Vegas recently.

The two stars chatted about Smurf hangover (Smurfovers, naturally), Smurf prostitutes (Smurftitutes), Smurfing up (uh, just watch and see), their favorite non-Smurf blue things and more. Check out the video above.

"The Smurfs 2" hits theaters everywhere Wednesday, July 31.
