The Teen Mom OG star, 25, and her pals headed to Liquid Pool Lounge at Aria Resort and Casino at about 12:30 p.m. on Saturday, September 3, where they sipped on champagne and danced by the pool.

Bookout was all smiles at the daytime hot spot as she stunned in a royal blue bikini, which she fittingly paired with a white and gold "Bride" hat.

"Sorry Mom! #GingersLastBinger," the MTV star captioned a slow-motion Instagram video of herself twerking with a bridalesque bow on her backside.

The night before, Bookout kicked off her bachelorette weekend at 1 Oak nightclub in Las Vegas in a cute white minidress, which she completed with a black "Mrs. McKinney" sash.

The reality star certainly has a lot to celebrate. In May, she and fiancé Taylor McKinney welcomed their second child together, son Maverick. (Bookout is also mom to son Bentley, 7, with ex Ryan Edwards and daughter Jayde, 15 months, with McKinney.)

Earlier this year, Bookout told Us Weekly that she found out she was pregnant with her third little one in January, just two days after McKinney proposed. The happy couple, who plan to tie the knot in October, revealed that they aren't expanding their family of five anytime soon.

"There are going to be some permanent birth control decisions made," the bride-to-be told Us in February.
