Washington, Feb 6 : Daniel Radcliffe finds it "weird" that celebrities feel the need to connect with one another, even if they have never met before.

"I still go, `It's you!', I can't help it. But there's this weird thing sometimes between celebrities who don't know each other. You have a shared experience of something so there's kind of an obligation to say hello," Contactmusic quoted him as telling Esquire magazine.

"I was in a coffee shop once and Jack Black came in and sat down and we did a, `Hey mate'. It was so weird. I've never even met the guy," he said.

Despite his fame, the 22-year-old actor insists that he finds it easy to make friends as he can always tell if someone is only interested in his success.

"It's f***ing easy to tell if people are genuine or not. Sometimes they're a bit too interested. If you take a step back and they pursue, then they're probably just a little bit too keen," he added. (ANI)
