On last night's finale of Season 2 of MTV's The Hills, we saw Heidi Montag (right) move out of the apartment she shared with Lauren Conrad (left) and move in with her much-reviled boyfriend, Spencer Pratt - to the disgust of Conrad and everyone here at The Hollywood Gossip.
Minus Miss Montag, the cast of The Hills - Audrina Patridge, Whitney Port and Lauren Conrad - stopped by MTV's TRL in New York to chat about the season finale of their hit reality show, which aired that night.
They didn't reveal too many details, but sources close to the cast report that a lot has gone down between the former roommates since the dramatic moving-out episode.
"Lauren and Heidi are no longer friends," a Hills source tells Us Weekly. "They never talk or hang out. Spencer achieved his goal and broke them apart."
This budding celebrity feud heated up even more Monday, when Montag ditched out on MTV's invitation to attend The Hills: Finale After Party - filmed before a live studio audience at MTV Studios in NYC last night.
During the broadcast, when host Susie Castillo asked Lauren Conrad how her friendship is with Heidi since The Hills concluded, she replied bluntly, "It's definitely different."
So why did Heidi Montag decline to join fellow Hills stars LC, Audrina, and Whitney (pictured below) at the after party show? A source close to the brash londe says she opted to stay back in Los Angeles with Pratt, who was not invited.
"Heidi was offended they wouldn't invite Spencer," says the source.
We're stunned that MTV didn't want that dirtbag on the air any longer. Anyway. Despite everything that happened, Lauren Conrad has not officially ruled out a reconciliation with her former BFF.
Asked whether she and Heidi could be friends again if she breaks up with Spencer Pratt, Conrad openly said it would be possible - and likely.
"Of course, I love Heidi. I was in a similar situation with her last year when I moved out with my boyfriend [Jason Wahler]. Heidi and I barely talked, but as soon as we broke up, she was there for me, and it only made our friendship stronger."
Meanwhile, Pratt and Montag are still shacking up in a Hollywood apartment.
"We're going to take over the world," Pratt recently told Us Weekly. "Heidi is the biggest star from that show."
Not if we see you at Hyde and beat you down first. Ass.
