Vanessa Hudgens
Vanessa Hudgens is an American actress best known for her work in High School Musical, the 2009 mega-bomb Bandslam and for taking nude pictures of herself. She is incredibly popular among both nine-year-old girls and autistic manchildren.
Joshua Martinez used her identity to troll Chris. Chris, being the humble human being that he is, found it absolutely reasonable that a highly attractive and popular movie star was sexually interested in him.
Since Vanessa told Chris she wrote her own Wikipedia biography, Chris felt that he had a righteous claim to do so as well. On 5 June 2009, after failing at his attempt to write his own Wikipedia biography, Chris tried to get a section on his supposed relationship with Vanessa Hudgens added to her Wikipedia page. Using the now-banned username of Sonichusaysyeswecan, Chris stated that "Vanessa and I are very close friends, and we have been working together much as of late. I think that this should be mentioned in the article." His request was ignored.
In KCWC Top 10 Dedication Special, he admits that he finally realized that he really was not talking to Vanessa Hudgens. He also admits that "Vanessa" always used Joshua's screenname when talking to him.
