She's become just as well known for her racy, provocative clothes choices as for her music.
But Rihanna went in a completely different style direction during New York Fashion Week on Sunday.
Looking more frumpy than fashionable, the pop superstar wore a distinctly unflattering knee-length grey dress and flat shoes as she attended the Opening Ceremony show.

Having ditched her usually sexy attire, Rihanna seemed like she was trying out something a little different as she took her place on the front row - although, unfortunately for her, the ensemble failed to impress.
The Diamonds singer, 25, who can usually pull off the most bizarre of outfits, managed to deliver a fashion fail just hours after she's stepped out in a stylish denim cut-offs and sports jacket.
She paired the vintage-style tea-dress with a sheer black stockings, pulling the hem up at various times to reveal her suspenders.
But instead of adding some equally retro, dainty footwear, Rihanna decided to mix things up with a pair of seriously clumpy but on-trend shoes.
The star then accessorised the look with a large black choker around her neck, and a splash of dark, plum lipstick.
Perhaps trying to fit in with the other guests who were watching as the uber-trendy label debuted its new collection, Rihanna looked like she'd tried to be as quirky and alternative as possible.
The singer was sporting the same mullet hair-do that she'd shown off he day before, looking slightly incongruous paired with the 1940s-style tea-dress.
Rihanna had caused another style stir when she stepped out during the day, going braless underneath her personalised jacket.
