Joaquin Phoenix has laughed off reports his singing career is a publicity stunt.
The actor, 34, announced he was quitting the big screen last year to pursue his music career.
And US reports have suggested it's a prank.
‘The transition from one career to another is never seamless,’ his rep Susan Patricola tells MTV.
‘It should come as no surprise to anyone that Joaquin came from a musical family, in addition to winning a Golden Globe for his portrayal of Johnny Cash.
'He intends on exploring his musical interests despite speculative, negative or positive reactions.’
Joaquin, who is currently sporting a substantial beard, performed an impromptu rap at Las Vegas club LAVO on 16 January.
