Finally, something pretty wild happened during Justin Timberlake‘s bachelor escapade!

After partying until dawn and being a “good boy” during his bachelor party in Vegas last Thursday, Jessica Biel‘s singer-actor fiancé brought his all-male entourage with him for a weeklong pre-nuptial bash in Mexico.

That’s where the NSync boy band member finally let loose, flashing a “partial crack” while his friends showed their butts while paparazzi went trigger happy.

We’re as curious about their wedding date as we are about their their next crazy stunt.

See Justin‘s glorious butt crack here.
