Kane Brown and Lauren Alaina have been trading favors and duets since they were kids singing together in middle school choir. Now, nearly a decade after their first collaboration, one of those favors is still outstanding, and Alaina says she is finally ready to settle it. To mark the achievement, Brown and Alaina agreed to get matching diamond tattoos, a tradition Brown had already started after an earlier song of his, "Heaven," reached Diamond status. Brown followed through right away, but Alaina's half of the pact has taken longer to fulfill. "Now that we've put out another song together, I'll go get my diamond tattoo," said Alaina.
