Despite spending four late-night hours with him, Rihanna is denying any possible romance or hook ups with Ashton Kutcher.

At a recent press conference for her debut movie BATTLESHIP, Rihanna was asked if Kutcher would be joining her in London for her promotional tour.  She called the question “disappointing,” saying, “I am happy and I’m single, if that is what you are asking.”

Earlier this month, Rihanna dropped by Kutcher’s L.A. mansion around midnight one night, and left at 4am.

Maybe it was just all for girl talk…
