The Blabbermouth story did not provide a source for this story, so this is unconfirmed at the moment. Below is the full Blabbermouth report:  

LIMP BIZKIT have received help from former HELMET singer/guitarist Page Hamilton and KORN's Brian "Head" Welch during the writing/recording sessions for the group's brand new CD, Less Is More, tentatively due in the spring through Flip/Interscope Records. However, it is presently unclear if Hamilton and Welch's contributions will make the final CD, which is currently being recorded at a Los Angeles studio with producer Rick Rubin (SLAYER, SYSTEM OF A DOWN, RED HOT CHILI PEPPERS). 32 songs have reportedly been written for the new album, with the bass and drum parts on some songs having already been recorded, leaving frontman Fred Durst to lay down his vocals.
