What’s the one thing most people do when they’re about to get married? Why, go to Vegas, of course!

That’s exactly what Rachel Reilly did earlier this month, when the former Big Brother and Amazing Race star and her closest girlfriends traveled to Sin City for an epic Bachelorette party.

Of course, what happens in Vegas, stays in Vegas; however, Celebuzz can still share a few photos from Reilly’s trip, which you can check out in the gallery, above.

Celebuzz can also reveal that Reilly and fiancee Brandon Villegas’s Sept. 8 nuptials will be featured on an upcoming episode of My Fair Wedding, set to air Dec. 15.

The show will also air 14 hour-long episodes this season.

Reilly met Villegas while competing on the 12th season of Big Brother. They got engaged on Valentine’s Day, 2011.
