Karen Meyers, the mother of late rapper Mac Miller is urging his friends and supporters to boycott an upcoming unauthorized biography about the star.

“To artists, management & friends:,” Meyers wrote in the Instagram post. “There is a writer doing a Mac Miller biography that some of you have been approached about or will be [in]. This book is not authorized/approved by Mac’s family or Estate. We are not participating and prefer you don’t either if you personally knew Malcolm.”

Just last month, three men were arrested in connection with the star's death. 

According to the cops, Cameron James Pettit, the first man arrested over Miller's death, contacted Stephen "Stevie" Walter on the night of Sept. 4, 2018. Mac had asked Pettit for some percs, and Pettit agreed to supply him with "ten blues."

Police then say that Pettit contacted Walter to get his hands on the ten blues. Walter sent a runner to Pettit with the pills -- and Pettit delivered them to Mac at about 2:30 AM on Sept. 5 -- the rapper was found dead on Sept. 7. The runner was Ryan Reavis, the second man who was arrested and charged earlier this week.

Miller reportedly died after consuming counterfeit pills provided to him by the men.
