Justin Timberlake is enjoying his last days as a single man. Gossip Cop reported the former NSYNC member went to Las Vegas with a group of 25 male friends for a bachelor party ahead of his impending nuptials with fiancee Jessica Biel.

The "Bad Teacher" actor and his entourage kicked off the night at Sinatra Restaurant at the Wynn Hotel before heading to Surrender nightclub at the same hotel. Wearing a bowtie and fedora, he sipped cocktails and drank his own 901 Tequila.

Timbaland, who worked with Timberlake in some songs, happened to be in the club. He came over and gave his pal well wishes on his upcoming wedding. The group later continued the party at Tryst, another club in the building, and danced until the wee hours.

Justin, 31, and Jessica, 30, were revealed getting engaged early this year after dating on and off for more than four years. The couple celebrated their engagement with their friends that included Timbaland, Lance Bass, JC Chasez, Ellen DeGeneres, Portia de Rossi and Amy Adams.

There's no word on the wedding date. Of the forthcoming ceremony, Biel said she did "almost nothing" to prepare it. The "New Year's Eve" actress said last July, "I'm just enjoying being engaged." She added, "I do feel like there is a lot of time and nothing needs to be rushed."
