Mac Miller would have been 27 today and his family is struggling.

An insider said the rapper's immediate family is wishing he could be with them to celebrate his special day. They are said to be grappling with grief following Miller's death in September, but are comforted by the fact that he's with them "in spirit."

"Malcom's family wishes that he could be at home celebrating his birthday with them and being the center of attention like he always was, but they know he is still there in spirit with his big ol' smile," an insider told Us Weekly. "It's going to be a hard day for the family."

Miller's loved ones are leaning on one another while they come to terms with the loss.

"They mill Malcom more than words can describe, but they are grieving together and surrounding one another with love," the insider added. "It's all they can do."

The "Ladders" singer died unexpected in September. He was found inside his home hours after the fact. Miller's cause of death was later confirmed to be an accidental overdose on fentanyl, cocaine and alcohol.

At the time, sources told Us the family was "shocked and sad." Those closes to him recalled Miller as "a bright light in this world for his family, friends and fans."
