Tina Turner will perform in front of more than 40,000 fans at the Australian rugby league's championship game in Sydney in September.
Turner's performance will include Simply the Best, the song used as the theme song for the pro rugby league in Australia.
She has made a number of television commercials promoting the sport of rugby, including one with Australian rocker Jimmy Barnes.
Turner says she likes rugby because "it is a full-on macho sport with plenty of thrills and spills. I found that it was a real game. No pads. Real he-men."
