Rihanna left baffled after man proposed to girlfriend backstage at concert

London: Rihanna was left stunned when a man proposed to his girlfriend backstage at her concert.

The ‘Umbrella’ hitmaker has apparently been holding special photo opportunities with devotees backstage on her ongoing ‘Loud’ tour. But the singer got more than she bargained for when one male got down on one knee and popped the question before one recent show on America``s east coast, reports the Daily Star. Rihanna was snapped looking visibly shocked, but she cheered as the female fan said yes. ANI
