Most skin on show: Rihanna

Most skin on show - Rihanna?

Rihanna was never going to turn up at such a high-profile event without some flesh to flash. The sultry singer opted for a backless gown that dropped right the way down to her behind, and had a plunge at the front that would make your mother blush! That, combined with the thigh-high leg split... we think Rihanna could take the prize for 'most skin on show'!
