The England rugby team will receive a special send-off from supporters and English pop group Take That ahead of the World Cup.
On September 9, the players, coaches and management team will be hosted at The O2 Arena for a night of live entertainment.
Take That will perform an hour-long set with the help of a 48-piece orchestra, while 2014 Britain's Got Talent winners Collabro and soprano Laura Wright will also take to the stage.
During the Wear the Rose Live event, there will be interviews with the players in front of a 14,500-strong crowd.
England captain Chris Robshaw said: "The support that we get from our dedicated fans means so much to the team and they really can be the difference when we are out on the pitch. We are looking forward to the opportunity to personally thank our supporters at the Wear the Rose Live event this September."
Tickets will be priced from £20.15 to £85, and O2 customers can buy seats 48 hours before general sale via the Priority app.
