Rihanna has closed BBC Radio 1's Hackney Weekend festival with an extravagant performance. On a stage which design was inspired by ancient Egypt, the Bajan songstress cheered the concertgoers with her energetic performance, spectacular firework shows, and a special appearance from none other than her former mentor, Jay-Z.

Donning a black leather jacket and sexy hotpants that she paired with round-framed sunglasses, Riri delivered such songs as "Only Girl (In the World)", "Disturbia", "S&M", "What's My Name?" and "Rude Boy" among others. Jay-Z, meanwhile, joined her on stage for "Run This Town", "Talk That Talk" and "Umbrella". Riri wrapped up her set with her hit single "We Found Love".

Near the end of her performance, the former girlfriend of Chris Brown told the crowd, "This is history in the making!" She gushed, "Hackney. You guys are making this such a memorable show for me. They told me it was going to be crazy but I did not expect it to be like this."

Multiple artists who had performed earlier at Hackney were spotted enjoying Riri's 65-minute set during the closing of the festival taking place at London's Olympic Park. Jessie J, Florence Welch and Tinie Tempah were among 50,000 fans who watched the Bajan singer's performance. Beyonce Knowles was also seen showing up in the mosh pit during her husband's appearance.

The BBC Radio 1's Hackney Weekend festival, which ran for two days as part of the London 2012 Festival, was supported by more than 100 artists who performed across six stages. Among the other notable performers at the event were Nicki Minaj, Flo Rida, Rita Ora and Lana Del Rey.
