Joe Jonas has sparked rumors of a new romance after he was photographed with model Karlie Kloss at Prince William's charity polo match on Saturday.
 
The singer was among the guests in attendance at the royal event in Santa Barbara, California and appeared to strike up a fast friendship with Kloss, the face of top designer label Oscar de la Renta.
 
The pair even took a moment to slip into a photo booth together to snap a series of fun black and white shots, which show them laughing, making silly faces and gazing into each other's eyes.
 
Rob Lowe, Rosario Dawson, Orlando Bloom and Zoe Saldana were also present at The Foundation Polo Challenge and looked on as the British prince scored four goals to lead his team to victory.
 
Jonas has been single since splitting from "Twilight" actress Ashley Greene in March.
