You don't. Those photos are fake; they only pictures of them kissing will be stills from Harry Potter and the Deathly Hallows and they haven't been released - or leaked - yet.
during the kissing scenes...
he already has and he did not like it, he said it was like kissing his sisters
Yeah, they are. They are kissing in the end of the movie. When Harry, Ron and Hermione go fight with the Deatheaters.
Emma Watson first kiss was with Rupert Grint
he said it felt really weird kissing Emma because she was more like another sister to him
Rupert and Emma have a big kissing seen in the seventh movie so we will see then! But now they are just flirting a lot.
he never had a crush on Emma Watson
Yes, he said that kissing Emma Watson was like kissing his sister. It was weird for the both of them because they'd known each other for so long and had a sibling or best friend-type relationship, not a boyfriend/girlfriend relationship.
no
Not in Harry Potter and the Half Blood Price, no.
No they haven't.
Ofcourse yes.
