The actor was photographed getting close to Stewart during a Kings of Leon concert in Vancouver on Saturday during a break from preproduction on their third vampire film, The Twilight Saga: Eclipse.
But Pattinson remains adamant that he is a bachelor -- and he even wonders why he doesn't have a girlfriend.
He says, "I don't have a girlfriend. I don't know why. You always think you're going to get more girls after you've made a movie and it never happens. You sit there and you're like, 'I'm a big movie star and I want to go out with some models,' but I don't know why that doesn't happen.
"It's especially different in L.A. Most of the women there are actresses and by default that makes them a little bit nuts -- not that that's a bad thing. But I don't really have a type. Whenever I get asked who my favorite celebrity crush is, I have no idea."
