The Jonas Brothers singer and the stunning model were spotted getting cosy at the Santa Barbara Polo & Racquet Club on Saturday (09.07.11) - where Britain`s Prince William played in a charity match - and they seemed to be enjoying every moment of each other`s company.
Before the game, the 22-year-old heartthrob and the 18-year-old beauty posed for black-and-white pictures in a photo booth and in the last one they were gazing into each other`s eyes.
It seems Joe is now over his heartbreak following his split from actress Ashley Green earlier this year.
The couple, who were together for around nine months, called time on their relationship after their busy work schedules kept them apart, although insisted they were still friends.
A source said: "It was mutual and amicable."
Joe - who previously dated Taylor Swift, Camilla Belle and Demi Lovato - had praised Ashley for putting his "feelings first" and claimed he was very happy in their relationship.
He said: "I think what works about it with Ashley is she really puts my feelings first. She understands my busy schedule. She`ll fly out to my shows - she`s been to places in South America that I can`t even pronounce."
