New couple alert? Audrina Patridge and polo player Nic Roldan recently shared a romantic vacation at the Presidente Intercontinental Resort & Spa in Cozumel, Mexico.

"They walked along the beach holding hands and had some wonderful dinners together," a source says. "Nic likes her because she is a casual surfer girl," the source adds. "She is his type."

The duo also spent time together recently in Palm Beach, Fla., where Roldan gave the Audrina star a polo lesson as she filmed her reality show.
