Is kristen stewert and robert pattinson going out??

yes they are really going out and rumourss are flying around that he has proposed to her as well, but the dicrectors don't want them to go out because if they break up it will ruin their on-screen connection

I read they can not going out because they can lose their role in the film. (i think this is not true).
As for Taylor and Selena isn't true I saw at the crispy news on mtv that Taylor is going out with Taylor Swift

yes they are but it said on some website that he got caught dating another girl!

For me to know and you to find out...but I will never tell..

Yes they are dating

I think they did encontro, data for some time while the series was being filmed, but they broke up before Breaking Dawn.
