Scott Weiland relapse? Robert DeLeo says yes

A Scott Weiland relapse is causing problems on the Stone Temple Pilots tour, STP bassist Robert DeLeo told Spin magazine.

The cause of this latest Scott Weiland relapse isn't heroin or cocaine, which the singer has battled before, but prescription pills, DeLeo said.

"He can't go on tour," DeLeo said. "He needs help. He thinks he's clean just because he's not shooting heroin. But he's popping pills."

The author of Spin's STP cover article, Stephen Elliot, also wrote that Weiland showed up late for a photo shoot and drank a "Scotch and Coke, heavy on the Scotch" during an interview at the singer's house. (The quotes from DeLeo about the Scott Weiland relapse are not in the online version of the article, but they are in the magazine.)

DeLeo's comments about the Scott Weiland relapse come as STP released its self-titled album today -- the band's first since 2001's Shangri La Dee Da -- featuring the hit single "Between the Lines." STP also has U.S. and European tour dates booked through the fall (including the KROQ Weenie Roast 2010), several TV appearances scheduled (including "Jimmy Kimmel Live" on Thursday night) and an unreleased song, "You Can't Drive Me Away," on the latest "True Blood" soundtrack.
