Rihanna, Katy Perry and Coldplay emerge as Super Bowl performance frontrunners

Rihanna, Katy Perry and Coldplay have reportedly emerged as the frontrunners to perform at the 2015 Super Bowl halftime show.

The musicians are under consideration to perform at the football game in Glendale, Arizona in February (15), but they are being asked to donate a portion of their subsequent touring income to the National Football League for the first time, according to the Wall Street Journal.

In the past, performers have not paid or been paid for their top billing during the sports telecast, but they have been compensated for travel and production expenses.

None of the parties have commented on the reports.

Bruno Mars headlined the halftime show earlier this year (14).
