R&B star Rihanna made one British fan's dreams come true recently after surprising her with a special visit following the launch of her new fashion collection.

The Umbrella hitmaker unveiled her sexy line for U.K. retail chain River Island at London Fashion Week last month (Feb13) and she returned to the British capital last week (begs04Mar13) as the designs hit store shelves.

As part of a River Island competition, one lucky woman was given the chance to try on items from the range before anyone else, and the singer decided to stop by the brand's flagship store on Oxford Street to meet the winner right outside of the changing rooms.

In video footage posted online, the young lady is left starstruck by the surprise, telling her pop idol, "(The clothes are) beautiful and you're beautiful as well. I'm in shock. Oh my god, it's Rihanna. I'm in shock, thank you so much..."
