Spencer Pratt Spews More Hate At Lauren Conrad

Spencer Pratt continues to spark controversy via his Twitter rants. The reality star launched an unwarranted attack at Lauren Conrad, after rumors have been circulating that she will be returning for some guest appearances on The Hills during the final 12 episodes of the MTV series.

Lauren has not responded to Spencer's word vomit — probably choosing to ignore the attack.

Heidi Montag has not reacted to her husband's crude remarks either.

Lauren left The Hills after the fifth season. She was the driving force being the reality show, which began documenting her big move to L.A., leaving behind her roots in Laguna Beach, Calif. and pursuing her dreams in the big city.

During her run on the show, LC famously fought with Spencer, her roommate Heidi's boyfriend, who she hated and who she blamed for ruining her friendship with Heidi.

Lauren also held the two responsible for spreading a sex-tape rumor about her.

While Spencer certainly does not want to see Lauren back on the reality show, L.C.'s former frenemy Kristin Cavallari told Regis Philbin and Kelly Ripa yesterday that she hopes Lauren returns!

"There aren't any set plans, but I think it would be great if she came back," Kristin said on Live With Regis and Kelly.

Kristin also opened up about Spencer getting booted off The Hills.

"Yeah, that's why he hasn't been filming," she said. "Oh god, I think its public knowledge; so, he threatened one of the producers and told her he was going to kill her."

"I mean, I only know so much because I wasn't there," she added.

Looks like Spencer is bitter that he's off and L.C. might be back on!
