Considering the starlet is one of E!'s main moneymakers, it almost seems like choice has been made!
BUT there's one other star who would like to join the contenders…
Singing the track Fresh Off the Runway from her album Unapologetic, she donned a skimpy pink lace Adam Selman outfit with a Lynn Ban necklace and adorably pink Manolo Blahnik booties.
Then, for her hit song Diamonds, she changed into a long black Vivienne Westwood skirt and matching corset.
Surprisingly, RiRi didn't wear diamonds, instead opting for a vintage pearl Depuis sunglasses, a vintage Chanel pearl choker, one Ellagem pearl earring , and long black lace gloves by Cornelia James.
Rihanna's black booties showed off her thigh-high nylons peeking out of the long slit in her skirt were made by Gucci.
In fact, a little more was peeking out of her….
Princess RiRi wasn't quite so princess-y when she accidentally revealed a little too much underneath that long skirt of hers.
Check out what we're talking about (below) then take a look at even more pictures from her performance, including pics with VS model Doutzen Kroes!
