US rapper Macklemore has called his performance of Same Love at the NRL Grand Final one of the "greatest honours" of his career.
Macklemore and Mary Lambert brought the house down when they performed the marriage equality song on Sunday night at Sydney's ANZ Stadium.
Macklemore took to Twitter after the performance to thank the NRL for giving him the chance to perform.
He tweeted, "Performing Same Love at the #NRLGF was one of the greatest honors of my career. Thank you @NRL for the opportunity & supporting equality."
Mary echoed his thoughts in a post on her own Twitter account, and promised to return to Australia.
