The Rihanna wheel continues to churn as she promotes her debut film "Battleship" around the world. This time the "We Found Love" hitmaker wasn't on a red carpet --she was spotted on a private yacht in Sydney Harbor hanging out with co-star Brooklyn Decker, along with Decker's friends Erin Andrews and Christine Teigen.

RiRi kept her fashion wear simple, rocking a loose denim shirt, while she relaxed on the posh looking yacht. She also had a brew.

What a beautiful life!
