Who did Bret michaels write every rose has its thorn about?

He wrote it about a Los Angelos stripper he was dating. One day he called her and heard another mans voice in the background. Her name was Tracy Crosby. He met her in 1984. She was 16 and met him outside the Tribidour (sp?) in Hollywood. They dated for 4 years. He wrote the song and gave it to her.
