Yes, She Twerked: Maci Bookout Celebrates Bachelorette Weekend In Vegas

#gingerslastbinger

Las Vegas is a prime destination for a good ol' bachelorette bash -- and Maci Bookout just feted her upcoming nuptials with her nearest and dearest gal pals in the Entertainment Capital of the World.

The Teen Mom OG cast member -- who will say "I do" to fiancé Taylor McKinney in the not-so-distant-future and is documenting her trip toward the aisle during this season of the long-running series -- spent Labor Day Weekend in Sin City and shared (some) memories on her Instagram.

"Cheers to my last weekend out as a "Bookout" - Vegas, I hope you're ready for me!" the Tennessean -- clad in a white dress and donning a fitting "Mrs. McKinney" sash -- captioned the selfie above, along with the hashtag #gingerslastbinger.

From there, Maci made her way to 1 OAK Las Vegas in the Mirage Hotel and Casino and posed solo on the red carpet. Looking glam, girl!

And she also took a glam pic with her ladies before dominating the nightclub.

Post-1 OAK, Maci and her entourage spent some QT at the Liquid Pool Lounge -- and the mother of three appropriately wore a "bride" hat and white tutu.

"Sorry Mom!" she added to the clip above, which shows her twerking to the beat.

And before the celebration came to a close, the star of the weekend shared one last update from REHAB Las Vegas.
