I agree about Sandra Bullock, she'd be cool cos she seems so naturally funny and down to earth and whatever and seems genuinely a sweet person.
I would either want to be Pink or Angelina Jolie I think.
Angelina because she is an amazing actress, funny in interviews, very down to earth( thought it was really sweet when she stayed outside for over two hours to sign autographs at a premiere), has such a cute son and is respected for her charity work etc without doing it for show or to gain publicity.
Pink because she's hot, hopefully guys would throw themselves at me, shes got a great voice and writes songs that I can relate to. Plus she again seems pretty down to earth, doesnt take herself too seriously and seems a lot deeper than I expected at first when I saw her in interviews.
Ok I just reread that and realised I talk crap but there you go.
