LONDON -- Rihanna riled up the crowd at Radio One's Hackney Weekend on Sunday night in East London as she closed out the festival with Jay-Z joining her on stage.
MTV UK reports that Ri-Ri, who wore a leopard shirt and cut-off fishnets, kicked off her set by screaming, "We got any freaks in the house?"
A slipped microphone pack mishap didn't cause her to miss a beat during the show. She simply asked a fan to re-attach it to her bra.
The star then said she was "going to break" some hearts "with a ballad," singing Love The Way You Lie.
In the wee hours of the morning, Rihanna was spotted leaving the Whisky Mist club still wearing her concert garb.
