Nicki Minaj joined Drake on stage at wet Wireless Festival drizzydrake.org

Nicki Minaj surprised fans by joining Drake on stage during his headline set at the Wireless Festival in Hyde Park.

The duo, who are both signed to Lil Wayne's Young Money label, wowed the crowd with a stellar performance of Drake's hit Make Me Proud.

For their duet, the female rapper poured her curves into a pair of clinging striped trousers and a midriff-baring striped turtle neck.

A grinning Drake could be seen admiring the view while she danced during their performance.

Drizzy Drake took the stage following an impressive set by Deadmau5's at a very wet Wireless.

Fresh from his gig at the Openair Frauenfeld music festival in Switzerland, the Canadian rapper performed a string of hits including I'm on One, Over and The Motto from his album Take Care.

In an earlier slot, Minaj treated the cheering crowd to tracks from her albums Pink Friday and Pink Friday Reloaded.

Living up to her diva reputation, she graced the stage 25 minutes late, complete with scantily-clad dancers to belt out the hits.

Thousands of fans braved the heavy rain for the three-day music event, which saw featured Professor Green, Example and Wiz Khalifa, among others.

New Roc Nation signing Rita Ora had kicked off the festivities on the mainstage and warmed up the crowd by singing her number one hit single RIP, along with some unknown tracks from her upcoming album Ora.

X Factor judge Tulisa Contostavlos also performed a medley of NDubz hits, as well as new tracks from her first solo album.

Clearly still pumped up from her recent sex tape scandal, the 23-year-old singer used her set as an opportunity to release some steam.

Before singing Titanium, she turned the air blue by launching into a rant about her ex-boyfriend Justin Edwards, who she blames for leaking the smutty video.

Dedicating the defiant ballad to him she said: "This is to my d**khead ex boyfriend, Justin f****** Edwards!!" GO T!"

Kanye West prodigy D'Banj played to a large crowd on one of the smaller stages at the sodden festival.

The Nigerian singer/songwriter proved to be one of the favourites of the day, with an impressive performance of his afrobeat hits Oliver Twist and Suddenly.

Pop superstar Rihanna closed the event, along with performances by Calvin Harris, Jessie J and Rizzle Kicks.
