The 26-year-old rapper was found dead at his home in Los Angeles earlier this month after suffering cardiac arrest following a suspected overdose and his ex-girlfriend Ariana, 25, has been listening to his new album 'Swimming'.
She shared two Instagram stories in which she revealed she had been listening to 'Ladders' and 'Dunno', which is believed to be about her.
This comes after Ariana broke days of silence to play tribute to Mac following his death.
She shared a video of him on Instagram and wrote: ''i adored you from the day i met you when i was nineteen and i always will.
''I can't believe you aren't here anymore. i really can't wrap my head around it. we talked about this. so many times. i'm so mad, i'm so sad i don't know what to do.
''You were my dearest friend. for so long. above anything else. i'm so sorry i couldn't fix or take your pain away. i really wanted to. the kindest, sweetest soul with demons he never deserved. i hope you're okay now. rest.''
Meanwhile, Mac's friend Shane Powers recently insisted Ariana was ''all about'' helping Mac get sober after the singer came under fire from online trolls who blamed her for Mac's untimely death.
Speaking on his podcast, The Shane Show, he said: ''They were very much in love and I have to say, she was incredible when he was first sobering up. She was a f***ing G to him. There could not have been anybody more supportive of him being sober than Ariana. I saw that, I was around it, I took phone calls from her. 'How do I help? What do I do?' This little girl was unbelievably involved and helpful to him being healthy. Whether he's an addict or not, the way that Mac partied was not healthy. And there was no one in his life more ready to go to the wall for him when it came to him being sober. She was an unbelievably stabilising force in his life and she was deeply helpful and effective in keeping Mac sober and helping him get sober. She was all about him being healthy. Period.''
Ariana and Mac dated for two years before breaking up in May. She is now engaged to actor Pete Davidson.
