Mac Miller, who passed away four months ago of a tragic drug overdose, would have turned 27 on Saturday, January 19. The day proved to be an emotional day for fans, friends and associates of the late rapper with many paying their tributes on social media.

Thundercat, Rex Orange County and Kehlani were but a few of the names to share heartfelt messages. Mac's ex Ariana Grande posted a tweet that simply read "miss u," although it has since been deleted.

It was revealed two days ago that Mac's parents would likely attend the Grammy's in his honor after his final album, Swimming, received a Grammy nomination in the Best Rap Album category.

Mac, real name Malcolm McCormick, passed away on 7 September. His death was attributed to an accidental overdose of fentanyl, cocaine and alcohol.
