Coldplay paid tribute to Prince during their concert at Rose Bowl in California on Sunday.
They covered the singer's "Nothing Compares 2 U" and brought James Corden on stage too!
Before introducing James on stage, Coldplay joked that James was once a member of the band. (untrue)
When they finished their performance together, they surprised James with a Happy Birthday cake on stage- how bad?!?!
Have a look!
