Iceman's out here melting hearts.

Drake linked up with TikToker NYFlavaaa Thursday for what the social media star thought was just a cool collab. But he walked away with a brand-new Escalade ... courtesy of Drizzy.

The creator has amassed quite a following by singing along to tons of Drake songs with his kids while picking up his daughter from school. And on the heels of his 3-album drop, Drake himself decided to get in on the fun.

NYFlavaaa's daughter is clearly shocked to see the rapper in the backseat ... but still manages to go bar-for-bar with him on his new song "Janice STFU."

And after the sweet sing-along, the TikToker revealed the Grammy-winner gifted him a Cadillac, choking up when he said ... "This motherf***er gave me an Escalade."

As far as why he just dropped a casual Caddy on the internet-famous family, Drake says ... why not?
