I sent a letter and SAE to Simon on: 25th May 2009, and today I recieved this photo back, it's different to his previous photos and it's a different sig, as he signed Simon Cowell on the others, and they were PP's, I'm not sure about this, but I'm leaning towards authentic.
address I used was:
Simon Cowell,
c/o Britains Got Talent,
Fountain Studios,
128, Wembley Park Drive,
Wembley
HA9 8HP
Great success Shaun
I was going to write to that address after I got an RTS fom his agent but I never got round to writing there... Wish I did now
Simon is amazing and I love BGT {love}
