However, despite praying that "good vibes" would get her to the concert after being hospitalised for tonsillitis, Miley was too ill to perform or even attend the bash.
"Here's how great Miley is: Miley was like — this is, like, day one after she has a 102-degree fever — 'I think I can do 'Landslide' because it's kind of...'," Ellen told U.S. TV show "Extra", before tailing off and admitting the singer had sent her a picture of herself at home as she continues to battle the throat infection.
In the end, Coldplay frontman Chris stepped up to the plate, with Ellen smiling: "He was like: 'I'm here anyway. I bought a table, so I'll just sing.'"
Ellen's wife Portia de Rossi took a video of Chris performing an acoustic version of Miley's 2009 tune Party in the U.S.A and shared it on Instagram, writing: "Thank you Chris for stepping in for Miley last night at #gorillapalooza You did her proud....#chrismartin @theellenfund."
