Late rapper Pimp C's mother has passed away, according to U.S. reports.

Weslyn 'Mama Wes' Monroe had been battling a serious illness in a Port Arthur, Texas hospital and reportedly passed away on Sunday (18Aug13).

A statement from Bun B, Pimp C's partner in the rap collective UGK, reads, "Thanks to everyone that has sent prayers and condolences. She was a great woman. Nurtured us from boys to men and made us strong enough to handle this industry.

"She was the one that kept us going when we didn't wanna go anymore. She was the backbone of Ugk, the definition of loyalty, the personification of unconditional love and the essence of what being Trill really meant.

"She's finally reunited with her son. God bless you both. RIP Mama Wes. You gave everything to make us Underground Kings."

Pimp C, whose real name was Chad Lamont Butler, passed away in 2007 in Los Angeles from an overdose of promethazine and codeine coupled with a preexisting sleep apnea condition.
