It's unacceptable that most people don't know the name Joan Smalls. Joan is a Puerto Rican fashion model who, according to Models.com, is currently the no. 1 model in the entire world! Though she's held that spot since September of this year, most people who don't follow the fashion industry are unaware of her hotness. But hopefully that's about to change, as she recently began co-hosting MTV's House of Style reboot.
