The 'Umbrella' singer, 25, wore a super-cute see-through rain hat as she left her London hotel yesterday (June 15).
Teaming the unusual head gear with a pair of cool sunglasses and practical but sexy thigh-high boots, Rihanna sure seemed prepared for the UK downpour.
Although usually only seen on grannies trying to protect their hair, Rihanna carried the hood off in style...
We predict the rain bonnet by Maison Michel might just sell out sometime soon... We certainly want one!
Rihanna is performing at Twickenham - alongside support act David Guetta - for the London leg of her Diamonds world tour, which saw her visit Cardiff and Manchester earlier this month.
