everyone who answered so far is WRONG! they are just writing what they think, but in reality, taylor DID date selena. he said a little while ago that he has a crush on selena. and since they were both flming different movies in vancouver, they got tegether. they were a bit shy about there relationship, but there are still a lot of pics of them together.

and they for some reason, people are saying they broke up. we're not so sure about this cause you can always trust the internet, but after a website said they broke up, there was pics of them together. anyway, then they were saying that they're single and that they broke up.

so its all confusing, but i think they broke up cause they're both very bussy people. (and plus taylor NEVER dated victori justice, i dont even think he dated anyone for a while except for selena)
