Rapper Eminem closes V Festival at Chelmsford in Essex
Eminem has closed this year's V festival in Chelmsford, Essex, with a performance featuring Rihanna.
The singer joined the US rap star on stage after performing for 70 minutes before him.
Rihanna performed the pair's single Love The Way You Lie in a black leather dress to thousands of festival-goers.
Over the weekend artists who also took to the stage in Essex and Staffordshire's Weston Park included Tinie Tempah, N-Dubz and Plan B.
Eminem, who was making his only UK live appearances of 2011 so far, played a fast-paced, hit-packed set which included early tracks like My Name Is and Stan right up to songs like Not Afraid from his most recent album, 2010's Recovery.
Rihanna warmed up the crowd for the Detroit rapper with a performance which featured a number of her hit singles like Umbrella and Don't Stop The Music.
Arctic Monkeys headlined Chelmsford Hylands Park on Saturday and Staffordshire Weston Park on Sunday.
Speaking to Newsbeat before going on stage the Sheffield band's bassist Nick O'Malley said: "It's a first for us.
"We don't really know what to expect, other than what we've heard."
"It could go either way," added drummer Matt Helders. "We've always been apprehensive about playing it, I suppose, than we were about arena gigs.
"We did them and that worked out. From how people describe it, it's a lot like doing one of our arena gigs, except with a lot more people."
Other artists who took to the stage at the Chelmsford and Staffordshire sites included Jessie J, who made an appearance on stage with her left leg still in a cast.
The singer broke her leg earlier this year while rehearsing for a concert in London.
During her set she dedicated a song to her parents: "Last year I was here in the crowd, I saw Florence (and the Machine) and said to myself, 'Next year I'm going to be there on stage.'
"And thank you to everyone for making it happen."
120,000 fans also enjoyed the likes of The Saturdays, Pendulum, Lostprophets, Bruno Mars, Razorlight and Ellie Goulding.
