Ray J's sources accuse Kim Kardashian of lying about being high on Ecstasy while they filmed the infamous sex tape

Kim Kardashian claimed on Sunday night's episode of Keeping Up With The Kardashians that she was high on Ecstasy when she filmed the infamous sex tape with Ray J years ago. But Ray J's sources say she's lying.

Kim claimed she took ecstasy while she was married to her first husband Damon Thomas. She also claimed she took the drug again when she filmed the sex tape with Ray J in 2003.

Ray J sources say Kim took no hard drugs nor did she drink alcohol during the filming of the sex tape. However, they say she smoked pot from a pipe shaped like a penis around the time the tape was made.

Ray J's sources told TMZ that he's offended Kim would suggest she did the sex tape because she was high. They say she was down with it from the beginning and all the way through.

But sources close to Kim told TMZ that the reality star stands by the claim she made on the show and she has nothing to gain from lying about it at this point in her life.
