Lily Allen restarted the party on Glastonbury's Pyramid Stage this evening after organisers temporarily pulled the power as a safety precaution following lightning.
The "Not Fair" singer performed in a racy pink jumpsuit and danced among giant inflatable milk bottles "because she's a mum".
She called President of FIFA Sepp Blatter a c**t and dedicated her song "F**k You" to him before announcing later on in her set that she had a "wedgie", pint in hand.
But while many fans cheered along both at Worthy Farm and in living rooms up and down the UK (particularly the "ladies" she repeatedly shouted out to), not everyone was enamoured with Allen's colourful set.
Here's a selection of some of the most-telling reactions during her set - the good, the bad and the ugly:
Lily Allen just stood on the Pyramid Stage, pulled out a wedgie and then announced it. I don't know what the hell is going on anymore.— Connor (@connorpwillis) June 27, 2014
Haha @lilyallen is a LASS. Drinking a pint on stage and correcting her wedgie! Whilst looking FIT. We love Lily— Lynsey Paterson (@LynseyDiva) June 27, 2014
Just watched Lily Allen set at Glastonbury, really good at times but an example of why trying to change doesn't always work #newstuffiscrap— snookerbacker (@snookerbacker) June 27, 2014
Blinding Lily Allen set at Glastonbury. Never knew she had a song about the war on drugs and another on oral sex (or lack of)— Cara (@ladylavan2012) June 27, 2014
Lily Allen is dogshit. Does anyone actually like her?— Dan Just (@justdanjust) June 27, 2014
maybe it was just the angle but that crowd looked so placid for Lily Allen— Ryan Valentine (@ryannvalentine) June 27, 2014
Remember when Lily Allen 'retired'? i miss that. #glasto2014— clatter-bones (@notwaving) June 27, 2014
