However, this is RiRi we're talking about. If she's not revealing various body parts, the singer's next port of call is her hair.

After going back to blonde last month, it's no surprise that the star has got bored with just the one hair colour. She was spotted with a mysterious black, diamond-shape on the top of her head when out and about in New York and after some consideration over whether she was wearing a hat/had forgotten to dye her roots, we're guessing this is more simply, Rihanna's new way to get noticed.

Thankfully, she's wearing a leather bumbag, encrusted with gold dollar signs, to distract us from the strange do.
