Christie Brinkley soaked a woman for "peeing on her rocks".

According to Erica, Christie screamed at her: "?'What are you doing?! You can't pee in front of my house! You have to go away. You're standing on my rocks. You can't pee on my rocks. I walk there!' "

However, Erica - who didn't recognise Christie at first - insisted the section of sand she was standing on, which was deserted except for a man who had also urinated there, was public property.

She told the New York Post newspaper she replied: "These are not your rocks. This is not your beach. The beach is public property. You don't own it."

In response, the former Sports Illustrated model then pulled out her hose and blasted the hairdresser from around 30 feet away.

Erica added: "I hadn't even peed yet, by the way."

After getting a soaking, Erica then defiantly relieved herself on the sand while being filmed by the model on her cellphone.

She said: "I would not have peed if she didn't spray me. After that, I kind of had to."

Christie - who only occasionally uses the holiday home - then called police, who interviewed Erica but declined to cite her.

Authorities explained to the publication that they wouldn't normally press charges unless the urination was witnessed by officers.

A local official said Erica had peed on public property.

A spokesperson for the supermodel has not commented on the incident.
