Rumours about the star's imminent departure from the show hit the internet on Monday (15Mar10), amid claims Pratt will be taking time out of TV to work in the cyber security division at American Defense Enterprise.
However, it has now emerged that bosses on the popular MTV series told Pratt to leave the show for a period of six weeks, according to UsWeekly.com.
A source tells the publication, "All of that stuff about him leaving The Hills to fight cyber crime is not true. He is leaving The Hills for six weeks because he was asked to.
"He got so crazy that he screamed at (the producer, saying), 'I should kill you for even asking me to do that!'"
Following a complaint from the producer, executives allegedly ordered Pratt to undergo an anger management program to ensure his future on the show, adds the insider.
