For his bachelor party, Justin Timberlake went to Las Vegas with a group of 25 friends, the actor and his entourage kicked off the night at Sinatra restaurant at the Wynn Hotel, before getting to the disco four jumps. The singer, who was wearing a bow tie and fedora, inspired by the Rat Pack group of actors, was seen sipping a cocktail and drink Tequila. The group then continued the party at Tryst, another club in the building, and danced until the wee hours.

Justin and girlfriend Jessica Biel have sealed their union earlier this year after dating on and off for more than four years. The couple celebrated their engagement in front of relatives and acquaintances that included showbiz star as Timbaland, Lance Bass, JC Chasez, Ellen DeGeneres, Portia de Rossi and Amy Adams.

Other sources contacted by OkMagazine reveal that the group has started the festivities in a private bungalow overlooking a tree-lined pool (the vegetation is made up of many palms). You do not have, however, news of his girlfriend. I have chosen a more intimate location to celebrate with her friends!
