Justin Timberlake just celebrated what may be more fun for most grooms than their actual weddings: the singer/actor/entrepreneur hosted a bachelor party in Las Vegas. So were there any 'Hangover'-style antics?

Not really, but it sounds like it was fun anyway.

Us Weekly reports that Timberlake, 31, and his all-male posse (there were about 20 gents in all) "took over the dance floor table" at Vegas' Tryst nightclub, which is part of the Wynn hotel. Reports say Timberlake and his pals danced and drank cocktails (including, obviously, Timberlake's own 901 Tequila) and were dressed to the nines, with the man of honor sporting a fedora (why?) and bow tie. Cute!

The group took the party elsewhere eventually, hanging out at the Wynn's pool. Did we mention the pool was packed with models? Still, sources insisted Timberlake, who was previously rumored to have a wandering eye from his uberhot fiance, Jessica Biel, "was a good boy" and that "it was just him and his guys." Smart man!

The 'Sexy Back' singer has had a busy week. In addition to his bachelor party, he also celebrated the release of his latest film, 'The Trouble With the Curve,' co-starring Amy Adams and Clint Eastwood. One thing he's not busy doing? Much to our chagrin, Timberlake's in no rush to record new music, which he explained has to be inspired by his own experiences. Here's hoping his wedding sparks some musical creativity in that busy brain of his!
