The Only Girl (In the World) singer expressed her love for London as she switched on the Christmas lights at Westfield shopping centre yesterday.
Rhi Rhi, who recently performed on X Factor, wore a red skirt and grey corset as she launched the official start to the festive season.
The 22-year-old was joined on stage by a group of children from the Help A London Child charity as she illuminated the centre.
Rihanna told Sky News: 'I'm very excited to be in London, and surprised that so many people have turned out to see me.
'I love London, maybe one day I'd like to have a home here.'
The Barbadian beauty added that she loves Christmas time because she 'loves gift-wrapping' presents for family and friends.
