The NFL has asked some of the world's biggest music stars to pay to feature during the 2015 Superbowl Halftime Show.

The event offers incredible exposure to whichever act is chosen to perform, and The Wall Street Journal reports that Katy Perry, Rihanna and Coldplay - the preferred choices of the NFL - have been asked whether they would be willing to pay for the privilege.

However, it appears the idea has not been well received by artists, with a source telling the newspaper that it got ''a chilly reception from the candidates' representatives''.

Historically, the NFL has not paid artists for appearing at the much-hyped Superbowl Halftime Show - but they have been willing to cover their expenses, which can be worth up to $1 million.

Bruno Mars and the Red Hot Chili Peppers appeared at this year's event and drew as many as 115.3 million viewers, compared to the 112.2 million who watched the game.

In 2013, meanwhile, Beyonce used the exposure generated by the Halftime Show to launch her 'Mrs Carter Show', her hit tour.

Super Bowl 2015 will take place on February 1.
