Macklemore apologises to Kendrick Lamar for 'robbing' him at Grammy Awards
Rapper picked up four awards at US ceremony, including Best Rap Album
The text was sent after Macklemore was handed the prize for Best Rap Album for his 2013 album 'The Heist' ahead of Lamar's 'Good Kid, MAAD City' plus Kanye West's 'Yeezus' and 'Nothing Was The Same' By Drake and was later published on Instagram by Macklemore himself.
Macklemore also took home Grammys for Best Rap Song and Best Rap Performance for 'Thrift Shop' as well as performing 'Same Love' with Madonna in a performance which saw more than 30 same-sex couples married live on stage.
Apologising to Lamar, Macklemore wrote: "You got robbed. I wanted you to win. You should have. It's weird and sucks that I robbed you. I was gonna say that during the speech then the music started playing during my speech and I froze."
