'Thrift Shop' hitmakers Macklemore & Ryan Lewis were champions in almost every rap category at the ceremony last month but thought Kendrick should have won the prize for Best Rap Album for his record 'good kid, m.A.A.d city'.
Macklemore decided to share a text he sent to the star on his Instagram account, in which he wrote, ''I wanted you to win ... It's weird and it sucks that I robbed you.''
Kendrick then responded to Macklemore's win, saying: ''It's well deserved, he did what he did, man.''
But Drake said the rapper's decision to share his text to Kendrick with the world was ''cheap''.
He told Rolling Stone: ''I was like, 'You won. Why are you posting your text message?' Just chill ... if you feel you didn't deserve it, go get better -- make better music. It felt cheap. It didn't feel genuine. Why do that? Why feel guilt? You think those guys would pay homage to you if they won?
''To name just Kendrick? That shit made me feel funny. No, in that case, you robbed everybody. We all need text messages!'' he added, after he was also nominated in a number of the same categories as Macklemore & Ryan Lewis.
Along with the award for Best Rap Album for their record 'The Heist', the rap duo also picked up gongs for Best New Artist, Best Rap Performance and Best Rap Song Title for their hit 'Thrift Shop'.
