Revellers have avoided muddy conditions so far despite occasional light showers as Bestival enjoys its 10th anniversary party.
Fatboy Slim has been announced as the final headliner for Bestival's 10th anniversary event.
The 49-year-old joins other headliners Elton John and Snoop Dogg in signing up for the five-day festival held on the Isle of Wight in September.
The Praise You star, who will perform the set 'Fatboy Slim's Bestival Birthday Bash', said: "It was at Glastonbury 2003, where I closed the Sunday Best stage for Rob da Bank (Event organiser and Radio 1 DJ) , that I first saw the glint in his eye to create his own festival.
"Here I am again, throwing them the biggest birthday bash possible and sharing the main stage alongside Elton John and Snoop Dogg. It's an absolute honour to return for this momentous occasion, staying creative and independent in these times. You've come a long way, baby."
MIA, Franz Ferdinand, Flaming Lips, The Knife, Wu-Tang Clan and Carl Cox are among the other acts to perform at the festival which was voted the UK's Best Major Festival last year.
A woman suffered a shock when her boyfriend proposed to her in a message shown on the screen of Bestival's main stage.
Viv Craske pre-recorded the proposal to be shown to his partner Jenny Engvall at the conclusion of the Bat For Lashes set at the festival on the Isle of Wight. Miss Engvall, who bakes cakes for a living, said yes.
Mr Craske, 38, said: "I wanted to do something special for the proposal. We came to Bestival a couple of years ago and saw Jenny playing with a friend's son and I realised I wanted to have children with her and we now have a son, Jasper who is 20 months.
"As we were coming back to Bestival I felt this was the place to propose as this is the place where we first became a family. I have been nervous all weekend waiting for this. I chose this moment because it was before Sigur Ros who is our favourite band."
Miss Engvall said: "It's fantastic, I am completely surprised, just shocked."
