UGK’s Bun B is always going to ride for his late partner. The hip-hop veteran went to social media this week to remember Houston rap legend Pimp C.

Bun B went to Instagram last night with a vintage pic of himself alongside Pimp.

A few days ago, Bun celebrated UGK’s now-iconic Ridin’ Dirty album.

Last December, Bun hit up IG with thoughts on the 11-year anniversary of Pimp’s death.

Pimp C passed away December 4, 2007 while booked to perform in Los Angeles.

An overdose of cough syrup and a preexisting sleep apnea condition killed Chad Butler, better known as rapper Pimp C, according to the Los Angeles County Coroner. His death has been ruled an accident. Butler was found dead in a Los Angeles hotel on Dec. 4. He was 33. He’d been in L.A. for a concert with rapper Too $hort. Though early reports suggested the cough syrup was over-the-counter, assistant chief coroner Ed Winter said the Promethazine/Codeine found in his system was from a prescription-based product.
