What happens in Vegas doesn't stay in Vegas if you're Justin Timberlake. After partying with pals in Sin City on the first leg of his bachelor party, the singer moved on to Cabo San Lucas.

Timberlake hasn't revealed the exact date of his wedding to Jessica Biel but he's sure having fun in his final days of bachelorhood.

As Breaking Celebrity News reported, Justin celebrated Thursday night at Surrender Nightclub at the Encore Las Vegas where he and his buddies were dressed to the nines in Rat Pack themed suits.
