All eyes are on controversial rapper Kanye West as he begins his highly-anticipated headline set at Glastonbury Festival.
The rapper and hip hop artist is performing on the world famous Pyramid stage, which has hosted some of the most memorable rock performances of the past 45 years.
News that the abrasive singer, who is sometimes prone to bizarre on-stage rants, was given the slot received a mixed reaction from fans, some of whom felt it was too much of a departure from the traditional Glastonbury roots.
Earlier supporting act Pharrell Williams stole the show with a lively set which saw him welcoming audience members on stage for a dance, while children joined him for his encore - hit song Happy.
A clearly emotional Williams showed off his A-list support with actor Bradley Cooper, Coldplay lead singer Chris Martin and F1 driver Lewis Hamilton cheering from the side of the stage.
The RnB singer had the crowd warmed up for the unlikely headliner West.
Co-organiser Emily Eavis also revealed she was targeted with online abuse and death threats following the announcement.
West earlier flew in to Glastonbury by helicopter with his reality TV star wife Kim Kardashian.
But the Grammy-award winning star's powerful stage presence could help him win over the audience.
Celebrities spotted soaking up the diverse Glastonbury atmosphere today included singer Adele, designer Stella McCartney, actor and presenter James Corden and recently retired footballer Rio Ferdinand.
Paloma Faith wowed crowds with her set, looking glamorous in a tuxedo-style dress and cat ears, while Jessie Ware, Kate Tempest and George Ezra were among the other highlights of the day.
The 135,000 campers enjoyed glorious sunshine but muddy fields following downpours yesterday mean they can not kick off their wellies just yet.
Last night Florence and the Machine, the first headliner of the festival, stunned crowds with a theatrical performance which ended with her stripping to her bra and running of stage.
Singer Florence Welch silenced any concerns that she was not up to the top slot, handed to her at the last-minute after Foo Fighters were forced to pull out.
During her unshakable performance in front of a roaring crowd of tens of thousands, she dedicated a cover of Foo Fighters "Times Like These" to lead singer Dave Grohl who was forced to pull out of the showpeice last week after he broke his leg.
Meanwhile Avon and Somerset Police said 54 arrests have been made by officers, mainly for drugs offences and thefts from tents, while 100 crimes have been reported.
A number of people have been taken to hospital with traumatic injuries such as broken legs and dislocations after falling over in the muddy fields, the South Western Ambulance Service NHS Foundation Trust said.
The mixed weather has also seen campers treated for sunburn and heat stroke. In total 118 people have been treated for injuries on site by the ambulance staff , with 19 taken to hospital.
