The video begins with Lily on the operating table, being put back together as a pop star after her years away.
But as the song begins, it's clear that she is back with things to say.
She then throws off her scrubs and morphs back into a fabulous pop star.
As the song explodes into a classically Lily electro-ska-pop riot.
She then uses all of her satirical prowess to skewer the objectification of women in pop music.
She does address this actually: "If you can't detect the sarcasm you've misunderstood."
We should repeat, it really is a very good song.
She then licks a banana suggestively, taking the piss out of Miley et al with her sarcasm further.
Incredibly, she then dances across a row of balloons that spell out "Lily Allen Has A Baggy Pussy".
Now that's all a bit more fun than the John Lewis ad, isn't it?
