1. First, what we gotta do right here is go back — back to when Ari and Mac started talking, **sigh,** on Twitter.
2. The aforementioned duet was released a few weeks later, just in time for the holidays — and oh yeah, it just happens to be THE MOST SENSUAL Christmas song ever.
3. Then, in 2013, their professional collaboration ramped up in "The Way," which was released as the lead single for Grande's first studio album, Yours Truly.
4. But yeah, about that chemistry though... **fans self vigorously**
5. And in 2016, Grande and Miller teamed up once again, this time for Miller's fourth album, The Divine Feminine.
6. And the rest was history: by the publication of her 2017 Cosmo cover, Grande opened up about their relationship, and all Mac & Ari shippers lost their minds.
When asked, "So how did you know it was the right time?" Grande said: "The universe, man. She was belting in our ears." BRB melting.
