I met him many times.
I first met Corbin at the High School Musical Tour in 2006. I met him again at some meet and greet he did at some music store during the release of his album. I met him in 2009 for his 2nd album release. I met him again in 2010 for his Broadway show and that's where he talked me for a while. He gave me bisexual teas. Good sis kept calling me sweetie and sweetheart. I felt more straight than him. I always met him in 2012 for godspell.
He is very nice but I've heard stories about good sis.
