Justin Timberlake has a bachelor like party in Las Vegas.

No one is sure if Timberlake and 25 of his closest buds were celebrating the actor-singer’s last days as a single man or not, but it sure looked like it.

The Trouble With the Curve star has been dating fellow actor Jessica Biel for five years, so no one was surprised when word got out of their engagement after Timberlake popped the question over the holidays in December 2011. Since then the couple has been pretty quiet about when and where the big day will take place. Biel even said, “I do feel like there is a lot of time and nothing needs to be rushed.”

One thing that couldn’t wait was an obvious guy getaway for Timberlake as he and the gang did Vegas the right way, in style. All the guys dressed to impress in Rat Pack inspired suits as they hit the Wynn’s Sinatra Restaurant for dinner. Then they made their move to Surrender Nightclub at Encore. Not to be contained for long, Timberlake and Co. stripped down to their swim gear and spent the rest of the night hanging in a private pool. An eyewitness said that Timberlake was well behaved while he tossed back his own brand of tequila, 901.

While the date isn’t known, it’s still breaking millions of little girls’ hearts to see the reality of Justin Timberlake walking down the aisle soon. Dear Jessica Biel, you’re a lucky woman…Don’t mess it up!
