Pop singer Rihanna and actor Josh Hartnett are not dating. Despite having shared a passionate smooch at NYC club Pink Elephant, the pair are just friends with nothing else going on, so claims Hartnett.

Speaking to US magazine the actor claims: "She's fun, she's a nice girl. We just met on TRL [last week]. I don't know her."

Regardless of whether he is dating the Umbrella singer - Josh is still thinking about the future. When asked how many children he wants, he exclaimed "three!"

He even has plans for his saving energy in his home when he does eventually have little tykes. "You can't have solar panels or windmills in New York, but I'm trying to make it as eco-friendly as possible."
