The former Stone Temple Pilots star was found dead on his tour bus in Bloomington, Minnesota shortly before he was due to perform in the town with his band The Wildabouts.

The 48 year old was recruited as frontman of rock supergroup Velvet Revolver alongside Guns N' Roses musicians Slash, Duff MCKagan and Matt Sorum in 2002, but he was fired in 2008 after repeatedly clashing with his bandmates over a number of issues, including his battle with substance abuse and run-ins with the law.

Velvet Revolver has been largely inactive since the acrimonious split, although they reunited with Weiland for a one-off charity show in 2012.

Despite their turbulent relationship, Slash has now taken to Instagram.com to remember Weiland following news of his death. He shared a picture of the singer performing onstage and wrote, "Sad day. RIP Scott Weiland."

Velvet Revolver's bassist Dave Kushner added, "RIP Scott Weiland."

Other musicians have taken to Twitter.com to add tributes, including Motley Crue's Nikki Sixx, who wrote, "Sad to hear about Scott's passing. I hope it wasn't drugs.The saddest part of the story is his kids and family being left behind. RIP" as his bandmate Tommy Lee posted, "Scott Weiland was just found dead on his tour bus... Very sad."

Veteran rocker Alice Cooper tweeted, "Deeply saddened by the passing of singer #ScottWeiland. What a voice we've lost. Thoughts and prayers to his family," and Rage Against the MAChine star Tom Morello added, "RIP Scott Weiland. May you be at peace and thank you for your music, Scott".

Good Charlotte star Joel Madden posted, "RIP Scott, Music is crying tonight", while a message posted on Wheatus' official account reads, "We opened for @STPBand (Stone Temple Pilots) in 2000. I watched them side stage & Scott Weiland destroyed me, he was the real thing. Seeing him changed me 4 ever (forever)."

The messages join tributes from Travis Barker, Joe Perry, Juliette Lewis, Nirvana's Krist Novoselic, Ryan Adams, Taylor Momsen, director Judd Apatow and comedian Chris Rock.
