Lauren Conrad vs. Spencer Pratt: It’s War!

“The Hills� hottie Lauren Conrad and Spencer Pratt, the fiancé and manager of her cast mate and ex-BFF Heidi Montag are still feuding

Fans of MTV’s reality series know lovely Lauren, 21, has long held Spencer, 23, responsible fro breaking her close friendship with Heidi, 20, and has always considered him an untrustworthy playboy. In a recent interview, Conrad spoke candidly about how it feels when “a friend stabs you in the back. I think the feud is beyond Spencer. At this point, Heidi has just done too much to me and I don’t need a friend like that.�

Now Spencer has fired back with both barrels! In a rambling posting on his personal Web site, Spencerpratt.com, he pulls no punches.

“I hate even talking about LC but she continues to talk about Heidi and I in all her interviews…so until she shuts her ugly mouth…I am going to continue to tell the world the truth about LC!� raves Pratt. “This is a WARNING to LC…she is starting a WAR that she doesn’t want!�

Spencer also takes aim at Lauren’s job as an intern at the L.A. office of Teen Vogue magazine, adding: “LC is a pathetic wannabe fashion designer who can’t even dress herself and look good!�

Pratt saves his most blistering words for the reported sex tap of Conrad and her ex-boyfriend, Jason Wahler, which Lauren has always denied existed – and which some feel Pratt leaked out to the press! Using derogatory slang for Conrad’s private parts, he writes: “IT’S SAD that she destroyed the SEX TAPE that DID EXIST…because those [privates] would have made her real FAMOUS! SO STOP TALKING ABOUT HEIDI AND MYSELF…YOU DO NOT WANT HEIDI AND I TO TAKE A PUBLIC LIE DETECTOR TEST ABOUT ALL THE THINGS WE KNOW ABOUT YOU AND YOUR [privates]!� Spencer later told Star, “Lauren has to just stop talking and shut up! This has gotten ridiculous! I’m sick of her hurting Heidi.�
