Bad Girl RiRi kept her fans waiting for more than three hours before she came on stage to perform a show in Monaco on Wednesday, in which attendees paid up to $782 a head. (Let's hope that Ri made it up to them by sharing some racy Instagram bikini photos.)
Without a slinky swimsuit in sight, Chris Brown's ex performed in a gorgeous white Balmain tuxedo mini-dress which looked like it was an updated version of Monroe's famous "Seven Year Itch" dress (without the drain grate.)
The controversial Barbadian beauty polished off her sexy look with thigh-high black satin boots, a colourful statement necklace and wavy hair à la Miss. Monroe. Although we don't think Marilyn would have shaved half of her head!
So what would columnist Liz Jones say about Jennifer Lawerence's BFF's outfit? The outspoken Brit probably wouldn't have anything nice to write about our girl Ri, but we love the "Diamonds" singer's chic ensemble.
Carry on, Rihanna!
