Exclusive | Justin Timberlake was out with pal, celebrity interior decorator…

We’re finally getting a clearer picture of the night Justin Timberlake was arrested for DUI.

One of the pals out with the “Sexy Back” singer in the Hamptons on the mid-June evening was his former business partner and wife Jessica Biel’s former stylist, Estee Stanley, several sources tell Page Six.

Timberlake was busted for drunk driving in Sag Harbor in mid-June after leaving tony classic, The American Hotel, where he allegedly had one martini.

Now we hear that the friends he was hanging with were top interior designer Stanley and her producer husband, Byran Furst.

Stanley previously styled Biel, as well as A-listers like Demi Moore, Brad Pitt and Penelope Cruz for red carpet events and the pair are still close friends.

She even hosted Biel and Timberlake’s engagement party at her own Los Angeles home in 2012.

Stanley is also a well-known interior decorator, working on the homes of Mary Kate and Ashley Olsen, Patrick Dempsey, Lea Michele and Timberlake and Biel.

In 2012 she launched a line of home goods with Timberlake called HomeMint. 

“This was really a collaboration with Estee,” Timberlake said at the time. “I don’t think I would do it if we weren’t in it together. We’ve known each other for a long time and have worked together on my homes—we really have a like-minded vision.”

In 2016, Staley and Biel, along with Greenleaf founder Jon Rollo, opened a kid friendly restaurant in Los Angeles called Au Fudge, that shut down in 2018.

Around that time she called Timberlake and Biel “practically my family.”

Timberlake swerved through a stop sign on the night of his arrest and was pulled over by a cop, who he famously told under his breathe, “This is going to ruin the tour,” sources told The Post.

When the young cop, who didn’t recognize the “Bye, Bye, Bye” crooner asked “what tour?” he responded, “The world tour.”

Stanley and her hubby had dinner with Timberlake that night and were with him at the American Hotel, we’re told.

According to reports, unidentified friends of the singer were following his car and were on the scene trying to convince officers to let him off.

Sources told TMZ that a woman asked officers, “Are you going to arrest Justin Timberlake?” and offered to drive him home. She was then allowed to drive Timberlake’s rental car back to her home after he was arrested, even though she had allegedly been drinking.

In September, Timberlake, who had refused a breathalyzer, pleaded guilty to a lesser charge of driving while alcohol impaired and was ordered to pay a $500 fine with a $260 surcharge, author a public service announcement, and do 25 hours of community service.

Biel was not there. She was in Manhattan filming an upcoming Prime Video series.
