We're really hoping TMZ is full of shit, but more trustworthy sources seem to confirm it's true. Check back for updates.

Update:
From Pimp C's publicist:
It is with great regret that I must confirm that Chad Butler aka Pimp C, one half of the legendary UGK, was in fact discovered dead this morning. Manager Rick Martin is asking that everyone please respect his family and those close to him at this time and refrain from rumors and innuendo.

Update: Pimp C's manager's statement regarding his death after the jump.

Los Angeles, CA - Manager Rick Martin, who was on hand this morning to identify the body of client and dear friend Chad Butler aka Pimp C, offers this statement regarding today's tragic loss:

This morning saw the loss of a man that was not only a client, but a very dear friend at a time when he had the most to live for. He was my best friend and I will always love him.

Chad's tragic passing leaves behind mourners the world over, including his mother, wife and children whom Chad loved more than anything. An official cause of death has yet to be determined.

I was so very proud of Chad and the growth he has shown since his release from prison; as an artist and business man and as a person. As one half of the legendary Texas group UGK, Chad was finally seeing the results of the years of love and labor that he and Bun B have put in over the years, culminating in the tremendous success of their album, Underground Kingz. Chad was set to soar with not only a new solo deal on Jive Records, but a lucrative publishing deal, a new satellite radio show, several group projects and a national cologne endorsement. Chad had everything to live for, making his unexpected passing a travesty.

Right now, my number one concern is the well being and livelihood of his family who are the ones most deeply affected by this loss. All efforts will be made to ensure that they are properly cared for in this tragic time and beyond.

As Chad's friend and manager, and on behalf of his family and those closest to him, we ask that you, the press keep reports of his passing to tributes to his amazing contributions as an artist and wait for the facts surrounding his death to come to light. Please let us all remember Pimp C as the kind and warmhearted man and rap music pioneer that he was.

Thank you,
Rick Martin / FM2 Inc.
