Dual Brownlow medallist and Australian of the Year Adam Goodes has broken his public silence on Eddie McGuire, saying the Collingwood president's racial slur last year was a friendship breaker.

Goodes spoke of his hurt at McGuire's gaffe at a business function in Sydney on Monday morning.

The Swans champion remains deeply hurt by McGuire, who said on air that the producers of King Kong should use the footballer to promote the musical.

McGuire's comment came just days after Goodes was called an ape by a young girl in a game against Collingwood during the AFL's indigenous themed round.
