While Rihanna is no stranger to controversy, the chart topper did manage to turn heads in one very interesting, if not bizarre number, on the red carpet during the 2015 Grammy Awards in Los Angeles on Sunday night.

The singer wore an unusual and massive pink Giambattista Valli gown. Arriving late and struggling to walk on the red carpet alone, the strapless dress had two tiers, which Rihanna accessorized with diamond earrings.

Other questionable looks of the night came from Giuliana Rancic, who showed off her painfully thin frame in a sequined pantsuit and turtleneck. The television host wore Louboutin shoes and jewels from Le Vian.

Another controversial look came from Madonna, who managed to flash her rear end in a one-piece leotard by Givenchy. The 56-year-old singer accidentally exposed her underwear while also exposing her chest in the skin-tight bustier. She accessorized her look with micro-net fishnets, black over-the-knee leather boots, shoulder pads and matching gloves.

And not to be outdone in the worst dressed department, reality television star Kim Kardashian wore a Jean Paul Gaultier robe that has everyone talking.
