The Celtic League champions have sold more than 15,000 tickets for tonight's friendly match against London Wasps and are confident of beating Swansea City's stadium record of 16,733.
More than 3,000 tickets were sold on Tuesday alone after it was announced that Charlotte Church - girlfriend of Ospreys star Gavin Henson - would be singing before the game.
Ospreys managing director Mike Cuddy said: "We've had an absolutely phenomenal sales period over the last few days and to already have the highest-ever crowd in the history of regional rugby in Wales is amazing."
