During Amos's show in Sydney on Tuesday (September 11), she improvized a verse in response to Spears's criticically panned performance at the MTV Music Video Awards.

Amos has previously spoken out in support of Britney Spears, saying that her head-shaving incident was an indication of who Spears really is.

Speaking to contactmusic earlier this year, Amos said: "I don't think her sweet, saccharine image was close to who she really was, and she rebelled."

The lyrics in full were:

Britney, they set you up
But you drank from their cup
Britney, they set you up
Oh, but this is what it looks like, love
This is what is looks like

When a star falls down, when a star falls down

Well, maybe you're a mother
But you still need your mother
Yes, I may be a mother but I still need a mother
To pick me up
Yes, to pick me up

When it all falls down, when it all falls down

Britney, they set you up
Is your contract winding up?
But you drank from the cup
Boy, this is what it looks like
Yes, I said, this is, this is what it looks like, Disney, yes

When a star falls down, when a star falls down

Well, maybe you're a mother
Baby, you still need a mother
Yes, I may be a mother but I still need a mother
To pick me up
Yes, to pick me up

When it all falls down, when it all falls down
When it all falls down, when it all falls down
