Coldplay: They'll be all yellow

Given that The Simpsons has already featured cameos from Bono and Tony Blair, the standard for getting onto the series has been clearly shifted towards "being well-known", so it was probably only a matter of time before Coldplay turned up.

Yes, more than ever confirming that "a cameo in The Simpsons" has become so prevalent that it's known as "following in the footsteps of Ed Begley Jr", Chris Martin and... uh, the others - is one of them called Tomsk? - will be drawn with overbites:

Chris Martin will play himself in the episode in which Coldplay perform a private show for Bart and Homer, after Homer wins a million dollars in the lottery.

Long-running sitcom featuring blue collar family winning big on the lottery resulting in a meeting with bizarrely popular English entertainers? What could possibly go wrong, eh?
