Love isn't dead after all -- NBA baller Kyle Kuzma and supermodel Winnie Harlow are officially dating again ... just five months after breaking up.
TMZ Sports has learned ... Kuz and Harlow picked up right where they left off earlier this month, deciding to give their relationship another try.
We're told the split wasn't ugly to begin with -- both sides kept in touch and remained friends during their time away from each other.
We broke the story -- the Wizards forward and "America's Next Top Model" contestant ended things back in August after more than a year of dating.
