Mama's got moves!

Teen Mom OG star Maci Bookout welcomed her third child — son Maverick Reed — with fiancé Taylor McKinney in May of this year, and now, the 25-year-old is ready for another major milestone: marriage.

The redheaded beauty announced her engagement to her longtime love in January, and recently headed off to Las Vegas with her girlfriends to celebrate her bachelorette party.

"Sorry Mom! #GingersLastBinger," the star captioned a video of herself twerking while wearing a bridal-themed tutu.

"Cheers to my last weekend out as a 'Bookout,'" she wrote. "Vegas, I hope you're ready for me!"
