Johnny Vieira says he is owed more than $2 million from a settlement agreed when Vanessa allegedly dumped him after shooting to stardom. The music producer claims he entered into a production agreement with aspiring star, to launch her career back in May 2005. He says the deal meant they would "share equally" the rewards from Vanessa's showbiz career.

Los Angeles-based Vieira claims Vanessa ditched him once she had landed her role as Gabriella Montez in 'High School Musical. But he says she has been violating a settlement deal agreed when they parted ways and claims he is owed more than $2 million. 

In court papers filed in LA Superior Court on Monday, Vieira provides a signed photo from Vanessa as "Exhibit A". The message on the photo says: "Johnny - thank you for everything. "Without you I would be nowhere. "We WILL make it BIG - Vanessa Hudgens. *Sweet!"
