Judges Simon, David, Alesha and Amanda were in town for three days of auditions ahead of the 11th series yesterday.
And fans of the ITV show waited lined up next to the red carpet from early morning in hope of meeting the famous stars as they arrived in the Midlands.
Sharon and John Aston, aged 57 and 61 respectively, who previously lived in Willenhall, travelled together to see the show.

John said: "We came to see it a couple of years ago and it was really interesting to see how they made it, and how few of the people who actually appear on stage never get anywhere near the TV programme.
"Only one act from last year out of 13 or 14 performances actually made it onto television.
"The klaxon that they press is so loud and makes everybody jumps every time."
Open auditions have already taken place for the shows after producers travelled up and down the country to host open try outs, while online audition submissions also took place.
Contestants will now face the panel in hope of making it onto the live shows.
The auditions started in Blackpool before travelling to London, Manchester and Birmingham.
Kimberley Buddle, 35, from Great Barr, said: "I'm a big fan of Britain's Got Talent and especially Simon Cowell.
I've met him a couple of times before at auditions and on the first series of Britain's Got Talent.
"I just want to see him in the flesh again, I'm not bothered about pictures I've got plenty.
"I like the comedians and I like watching ventriloquists.
"I'm a big fan of Walliams as well, he's really funny."
Carers and residents from the Three Roses care home in Hagley were excited to see Cowell arrive, and then the auditions afterwards.
Carer Sarah Thompson said: "We've come to Birmingham today to have some fun and see the show.
"I always watch it with my children but we've come today as a team to see it all!"
