[/quote]Firstly, the heart looks always the same, has been for years. Therefore, I really don't think it's sec,as people around her have changed so often that it is not likely that the same person has always been signing for her.
I do see that "B" looks different but perhaps she was in extreme rush and tried to sign as many photos as possible in a short time. I believe other similarities do make up for this difference.
Secondly, it can be seen that the VV siggies are done in rush which also shows that it was probably herself who signed. A sec would have plenty of time to sit down and do her best to fake an autograph (Sarah J Parker for example whose TTM's always look perfect). Some example scans:
The above is an older IP - heart looks very similar, B, ri and tney are written separately, just as my VV success.
This one is a TTM success from 2004, again great similarities. Even "B" looks as on ours.
Also, she hasn't been on a tour for 5 years and she doesn't normally sign (many) autographs, so I can't see any reason why she wouldn't reply to some fan requests. While abroad, she might have a bit more time between gigs to do that.
I understand that you are skeptical, as she is such a massive star but I personally have absolutely no doubt that her Circus tour TTM's are real.
hopefully it will come either today or tomorrow
