The world's most marketable celebrity has been named
It's not Joey Tribbiani.
A study by the NPD Group has revealed that Rihanna fans have more "distinctive brand preferences" than any other celebrity, which means Rihanna has 3.7 times the endorsement opportunities of the average celeb.
We have no theories as to why this might be.
Beyoncé, Usher, Wiz Khalifa and Ne-Yo made up the top five of celebrities who are best able to convince their fans to buy whatever they are hocking on TV.
A different study conducted by Repucom found that Taylor Swift is the best musician for brands to sponsor when it comes to concerts. Swift's concerts are particularly popular, owing to the fact that she regularly pulls out surprise guests to perform with her.
Repucom found that the other artists who are best able to sell products by gigging are Justin Timberlake, Lady Gaga, Katy Perry, and Beyoncé. Rihanna didn't make it onto this list, but that's probably because she hasn't been on tour in a while.
