You know you've made it big when you decide to talk business on a boat.  Actually, make that a yacht. In the middle of the glorious Mediterranean Sea. And this is exactly how Rihanna likes to roll.

The slimmed-down singer enjoyed the Mediterranean sun (and potentially men) all week – see her sexy pics - but decided for some vacation-timeout to talk business with rapper Tinie Tempah. The Barbados babe flew the UK singer out to her yacht to discuss collaborating together on a future track.

Keeping in line with her partying ways, Rihanna and Tinie partied the night away and who knows what else!

What singer would you like Rihanna to collaborate with?
