On Thursday night, Justin Timberlake celebrated his final days as a single man at a Bachelor party in Las Vegas, Nevada.

The singer/actor and 20 friends partied at Wynn Las Vegas and Tryst nightclub. DJ Spider spun some tunes while Justin, wearing a bow tie and fedora, drank tequila.

But the party didn't get out of control. A rep for the club told US Magazine, "The group was very polite."

Timberlake's fiance, Jessica Biel, reportedly hasn't had a bachelorette party yet. After dating for four years and trying to keep their relationship under wraps, Justin and Jess broke up in March 2011. But by the fall, the two were back together. They got engaged in December of the same year.

Timberlake stars in the new film "Trouble With The Curve."
