"Biggest bromance has got to be Boydy and Keano," Vokes revealed in a light hearted interview with the Premier League.
"They travel in (to training) together, they're inseparable in the dressing room - they can't get away from each other.
"They're very close and they get very jealous of each other as well when they're not together and one is playing darts with another lad."
Both players joined Burnley in the summer of 2014 when the Clarets were newly promoted to the Premier League.
They remained despite relegation and were both crucial parts of the promotion effort as Sean Dyche's team made an immediate return to the top flight for this season.
