Mac Miller's mother, Karen Meyers, has alerted fans about an unauthorized biographer soliciting information from the rapper's friend, fans, and former business partners.

"To artists, management & friends: there is a writer doing a Mac Miller biography that some of you have been approached about or will be," Meyers' Instagram message reads. "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."

Meanwhile, Mac Miller's family did authorize a celebration of life on the late rapper's birthday. This event was held at Pittsburgh's Blue Slide Park. Mac's father made an appearance during the gathering to offer his son's fans words of advice.

"Many of us who were young, including me, experiment with drugs. But it's a different fucking world out there," Mac's father, Mark McCormick, said. "All it takes is a little tiny stone of Fentanyl and cocaine and you're dead.... And the only thing I would say to you is: Don't take the risk. It's just not worth it."
