Stone Temple Pilots say they have "officially terminated" longtime frontman Scott Weiland.
No reason was given for his firing. The singer is set to begin a one month solo tour on Friday.
UPDATE at 12:20 p.m. PT: Scott Weiland has responded to the news. Check out his reaction here.
The news was announced on the band's website on Wednesday, February 27. The remaining members of the alternative rock band are guitarist Dean DeLeo, his brother and bassist Robert DeLeo and drummer Eric Kretz.
Weiland had helped form the alternative rock band in the late 1980s and recorded and performed with the group, which became known for 1990s commercial hits such as "Plush" and "Interstate Love Song," until the band members parted ways around 2003.
He then went on to concentrate on a solo career and also sang lead vocals for supergroup Velvet Revolver, which contained former Guns N' Roses guitarist Slash. Weiland and the Stone Temple Pilots reunited in 2008.
In December, Slash had told the Minneapolis radio show 93X that he was told Weiland "got fired from STP." Weiland denied this in an interview with Rolling Stone on Tuesday, a day before the band's announcement about his termination, saying: "I haven't quit. I haven't been fired. Slash doesn't know anything about STP."
Stone Temple Pilots' most recent major release was the 2010 self-titled sixth studio album. The group had toured as most recently as late last year.
