So Heidi and Spencer were banned from the after party of the Hills premiere, Lauren are you two, you are a z-list "star" in your own mind!

The Hills doesn’t premiere until Monday, but the drama is already in full swing!Heidi Montag and Spencer Pratt were "banned" from attending the MTV show’s post-premiere party Wednesday night in L.A., a show source tells Usmagazine.com, due to the couple’s escalating feud with costars Lauren Conrad and Audrina Patridge.In fact, the entire cast has now been prohibited from speaking about each other in the press, according to the source.While MTV allowed Pratt, 23, and Montag, 20, to walk on the red carpet, "they were not allowed to be at the party while Lauren was here," says a source, whoadded that extra security was also brought on.Another source tells Usmagazine.com that MTV "suspended" Spencer and Heidi from doing any more media to promote The Hills after their trash-talking interview on Monday with a Philadelphia radio station.While chatting with talk show hosts on Q102 FM, Pratt called Conrad a "stupid girl" who is just using the couple to draw attention to herself. "She’s thedouche, the psycho," he said.Montag added, "I never could be friends with some lowlife like that."The insider says that after the interview, MTV nearly canceled the couple’s appearance on On the Air With Ryan Seacrest Wednesday morning, but allowed them to do one last interview with the KIIS FM show. For now, however, "they are on a media blackout," says the source.Another insider says that MTV has decided to gag all parties -- including Conrad and Patridge -- on the subject matter. "Tensions were so high, MTV decided to shut it all down," says the source."Spencer crossed a line with several things he said. And fans of the show take it all so seriously, people were starting to worry about security concerns on all sides."
