Horses weren't the only ones being ridden in Santa Barbara this weekend, where a number of celebrities came out to watch Prince William in action at the Santa Barbara Polo & Racquet Club.
Joe Jonas was spotted at the event with Karlie Kloss, a 21-year model and the current face of Oscar de la Renta.
Joe Jonas + Karlie Kloss = Jarlie?
The rumored couple joked around inside a Jack Willis-sponsored photo booth prior to the match and looked quite cozy together during it, onlookers say.
This isn't the only JoBro with a new squeeze, either. Nick Jonas started dating Delta Goodrem a couple months ago, making it clear these two possess equal talent in the woman-attracting department as they do in the music department.
