Replying to Girl on Justin Bieber Video

Should I believe this girl thats says she was on Justin Bieber video Baby or not? I don't know what to do and I kind of believe her. I talk to her on the phone and met her on habbo.com. She the one that Justin Bieber runs after in a pink shirt with blue jeans on. Please give me some ideas on what to do. Here the link to the video to see for yourself and she pretty hot I must say. http://www.youtube.com/watch?v=kffacxfA7G4
