Spencer Pratt Admits to Starting the Lauren Conrad Sex Tape Rumor

Spencer Pratt is finally coming clean.

The 32-year-old reality star and his wife, Heidi Montag, sat down with Complex magazine and confirmed for the first time that he was the source of the ages-old rumor that Lauren Conrad had a sex tape with her boyfriend Jason Wahler. Conrad has adamantly denied the rumor that ultimately ruined her friendship with Heidi.

“Lauren is a cold-hearted killer,” Spencer says of his arch nemesis. “That’s what people don’t get. She will cut you in your sleep. She tried to destroy us. If you want to throw missiles, I’m throwing a nuke. This is how I operate."

Pratt also claims Kris Jenner asked him to manage Kim Kardashian before she rose to fame. "She can deny it if she wants, but she comes up to me and is like, ‘Spencer, I want you to manage Kim.’ I literally started laughing,” he says. While Kim’s rep denies this conversation ever took place, Pratt also insists that Kim used to work for him and Heidi. “Kim was edited out of 'Hills’ episodes organizing Heidi’s closet,” he reveals. “Now it’s like, 'Kim Kardashian breaks the Internet with her booty.’ Like, what the f–k?"
