I think it's real. It's hard to say. But I did asked a question about a family member and she answered it in a way I don't think a fake person would. Also the Myspace link is to her real Myspace page.
And Twitter has a policy about people posing as celebrities. There were people posing as members of the Kardashian family and most of those pages were deleted. If a person has a Twitter page and they are using a celebrity picture, but the content of what they are posting is not being done as the celebrity, then that's not an issue... i.e a fan of Michael Jackson using his picture as there profile pic.
