13th contestant emerges on access the stars

I think you may be referring to the popular TV show "Access All Areas" (not "Access the Stars", which doesn't seem to be a real show).

In that case, the 13th contestant to emerge on "Access All Areas" would be a surprise reveal, as the show typically features 12 contestants competing for a chance to win a unique experience or prize.

Could you please provide more context or information about the show and the contestant you're referring to? I'd be happy to help if I can!
