Rihanna and the Coconuts

Not content with selling millions of records, having her own perfume, being the face of Nivea and generally being very rich, Rihanna is now the face of coconut water Vita Coco. With Madonna and Red Hot Chilli Peppers' Anthony Kiedis as investors in the water brand, we’re sure it will be flying off the shelves.

Madonna said: “'Rihanna is a natural fit for the Vita Coco brand and I'm so happy to have her on the team.”

Personally, we can’t stand coconut water – we tried it numerous times in the West Indies and really tried to like it, but no. That said, it is high in potassium so would make a good sports drink. There are even reports of coconut water being used as an intravenous hydration fluid in some developing countries where medical saline was unavailable. Multipurpose then!

Vita Coco costs from £2.05 for 330ml to £4.65 for 1 litre and is available online and in store at Holland & Barrett.
