Rihanna is still in Hawaii enjoying her vacation and giving her fans sneak peeks along way by Tweeting messages about getting high and posting sexy pictures of herself in a bathing suit.

Never one to take the less-the-more approach, Riri spent last night making us jealous – again – by posting more pics, including one of her in a string bikini “exercising” on an elliptical machine. She wrote to Khloe Kardashian: “Haaaa!!! Come tap this.”

And when a fan asked what the “secret” was to having that flawless body, Rihanna kept it to herself and cleverly wrote back: “Angles/Lighting/Photoshop :)”
