Harry Potter lovebirds Daniel Radcliffe and Katie Leung had to lock lips a staggering thirty times on the set of the latest movie - just to perfect one kiss. The young stars, who play the boy wizard and his love interest CHO CHANG in upcoming installment ORDER OF THE PHOENIX, share their first love scene in the film but found screen smooching hard to master. Radcliffe, 17, says, "We probably got it on the thirtieth take. My god, it was fun. Me and Katie - we were awkward and nervous at first but once we got it, it was fine." Leung comments of her co-star's technique: "Daniel is a good kisser, I really enjoyed it. He's energetic and makes you feel relaxed."
