Justin Timberlake Arrives at Court to Plead Guilty, Looks Serious

Justin Timberlake just arrived at the Sag Harbor courthouse to enter his plea in his driving while ability impaired case, and the pop star ain’t smiling in the clip.

The singer-songwriter arrived in a navy blue sweater and brown-gray slacks, rose-colored sunglasses covering his eyes … and, a serious expression on his face as he marched up the stairs toward his hearing.

There’s a lot of shouting and yelling from photogs in the clip … and, someone asks if he has a message for his fans — though he chooses not to respond.

Not everyone’s in support of Justin though … at least one protester — holding a photo of a young boy, presumably killed in a drunk driving accident — is hanging around the courthouse. It’s possible she’s protesting the plea deal Justin received.

TMZ broke the story … JT plans to plead guilty to this lesser charge — a traffic offense, a way smaller offense when compared to the original DWI charge, and then officially put this case behind him.

While Justin’s charge has the word “impaired” in it, it’s not a drunk driving offense … and, we knew he’d only have to pay a small fine between $300 and $500 — barely even a slap on the wrist for the mega-rich star.

Justin’s driver’s license is suspended In New York … standard procedure for anyone who turns down a Breathalyzer like cops say Justin did back in June.

As we told you … Timberlake was arrested on June 18 after cops say he blew through a stop sign and failed to stay on the right side of the road. Cops say he failed all of the field sobriety tests and ultimately arrested him — releasing him the following morning.

Timberlake’s had to enter his plea of not guilty twice — getting arraigned a second time after his lawyers challenged the first set of charging documents because of some sort of error.

He’s since changed his tune and decided to plead guilty to the lesser charge.
