Ore meets the stars of Radio 1's Hackney weekend
Rihanna wrapped up BBC Radio 1's Hackney Weekend with spectacular fireworks and a guest performance from rapper Jay-Z.
Beyonce, Jessie J and Tinie Tempah were among 50,000 fans to watch Rihanna's live show.
Jay-Z had brought Rihanna into his set on Saturday, so the Only Girl In The World star did it the other way round in her set.
Just before finishing, Rihanna said: "This is history in the making."
Our very own Ore was at Hackney specially for Newsround.
He caught up with the stars, including Tinchy Stryder and Leona Lewis.
