Maci Bookout really let loose in Las Vegas this weekend, as she rocked out poolside for her bachelorette party.
The "Teen Mom OG" star took her celebrations to the next level by twerking in a white mesh bustle — and not much else! — at the the LIQUID Pool Lounge at ARIA Resort & Casino on Saturday.
The mom of 3 — who had a baby just months ago — let it all hang out in a pretty sultry video … and frankly, she's never looked better.
Maci donned a smoking blue bikini and the obligatory "Bride" hat for the festivities, arriving to the pool with a bevy of swimsuit-clad beauties. The bride-to-be sipped on champagne and showed off her dance moves while DJ Ruckus spun hits.
The 23-year-old Bookout was in high spirits all weekend, as she also partied alongside Scott Disick on Friday night at 1 OAK Nightclub inside The Mirage Hotel & Casino on Friday. The reality star showed up to the club sporting a white mini and a "Future Mrs. McKinney" sash, a nod to fiance Taylor McKinney.
Maci and her girlfriends were seen taking shots, sipping on champagne and enjoying a pink and gold cake inside.
Congrats to the bride-to-be -- we can't wait to see her wedding dress!
