Dang, girl! Alessandra Ambrosio shook what her mama gave her in a racy Instagram post on Thursday, September 15, proving that even Victoria’s Secret Angels have very human senses of humor.

“Working my A** off!!’ she captioned the fun video clip. “#theAProject @alebyalessandra #foreveronvacation @mangabaproducoes.”

In the fun, sexy video, Ambrosio, 35, playfully shakes her butt — which is clad in a bright turquoise swimsuit — smiling over her shoulder as Rihanna’s “Work” plays in the background.

The supermodel is currently in the Maldives for a photo shoot, and is working as a special lifestyle editor for Maxim to show how people can live "#foreveronvacation.” Ambrosio has been documenting her tropical getaway in a series of enviable posts to Instagram, including one on Wednesday, September 14, in which the brunette stunner shows off her lanky silhouette against the setting sun.

“Life is a 🏝BEACH🏝 @shangrilamaldives @mangabaproducoes @alebyalessandra 📸 @ingefonteyne #TheAproject #Maldives #foreveronvacation #paradise #motivationmonday ❤️🐚,” she posted on Monday, September 12.

The mother-of-two has to work hard to maintain her figure, however. In April, she opened up to The Edit about how she shed her baby weight at rapid speed following the birth of her first child, Anja, in 2008.

“I only had three months to lose all the weight,” the Brazilian model told the site. “And I was on this 1,200-calorie-a-day meal-delivery service that I hated. I couldn’t do that again.”

Thank You!

Ambrosio — who shares her two children with fiance Jamie Mazur — added that her gig with Victoria’s Secret is what inspired her to really start paying attention to her fitness. “In my family, no one ever worked out,” she said. “It wasn’t until I did my first Victoria’s Secret show that I started exercising. Now that it’s a healthy, normal part of my daily routine, my kids will grow up seeing it in the same way, and I love that.”
