As we now know, Mac Miller tragically passed away from a drug overdose last year.
Since then, Ariana has been paying tribute to her lat ex-boyfriend in every way she can... so when this anniversary came up, she made a very adorable post on Instagram story.
The song wasn't only the start of a relationship that would blossom between the two, but also help catapult Ariana's career to what it is today.
Ariana later posted a pic cuddling her dog, Myron, which she and Mac got together.
