AceShowbiz - Police allegedly were tipped off by an informant at hotel before Justin Timberlake was busted for DWI. According to a new report, someone who was at the swanky Hamptons hotel, where the singer hung out with friends prior to his arrest, called cops because they were concerned he would get behind the wheel.

A local eatery owner told the New York Post that the informant called the cops from Sag Harbor's American Hotel and told them that the "SexyBack" hitmaker had "a lot of drinks" and might be climbing behind the wheel to drive himself home.

"They said Justin was having a lot of drinks, and they told the cop to watch him if he is going to drive," the source, who was described as a "well-connected Southhampton restaurateur", told the outlet on Sunday, June 23.

The local business owner did not specify whether the caller was an employee or patron of Sag Harbor's American Hotel, but insisted that Justin was "definitely treated unfairly." The source claimed, "Everyone drives through that stop sign when no one is there," noting that the 10-time Grammy winner and married dad of two young boys was a "Hamptons regular" who has frequented his establishments "many times" over the years.

"He was always a gentleman," the restaurateur said of the star. "People always recognize him, and they ask him for a picture, and he always says yes. He has the hat pulled down and the sunglasses, so it's hard to recognize him, but some people do."

"He's not like [Leonardo DiCaprio]. Leo does not like to be recognized, and he will even curse. He does not take pictures, especially if he is with a bunch of models," the restaurateur said.

The source also didn't buy the reports that rookie cop Michael Arkinson, who pulled Justin over, didn't recognize him. "If you live in America, you know who Justin Timberlake is," the restaurateur stated. "The cop did his job, but he definitely knew who Justin was."

Previously, a local law enforcement source told the site that Justin was stopped twice by the same officer before he was eventually arrested on early Tuesday morning, June 18. "He was stopped and advised not to drive," the insider said. "The officer didn't recognize him; he's a young guy. And he still gave Justin a break, because he didn't pose an immediate danger."

"What a dumba**," the insider slammed the former NSYNC star. "I am thinking he could afford a driver. How's that for entitlement?"

Meanwhile, Hamptons residents who were also pulled over by the young cop in the past dubbed the 23-year-old the "Sag Harbor Nazi" and "little redheaded dips**." One resident said of his experience, "I was surprised he pulled me over. It was off-season, and no one was around." The same person added, "It was a d**khead move. I felt like he pulled me over just for the sake of doing it."

In other news, a video of Justin seemingly "under the influence" at his concert in Las Vegas last month resurfaced in the wake of his DWI arrest. Many social media users claimed that the 43-year-old's wide-eyed gaze might indicate he "had something in his system" in the clip.

However, sources have debunked the speculation, telling TMZ that the "Cry Me a River" singer was sober as he has always been for every show.
