The 29-year-old Aerie model, who is pregnant with her first child with boyfriend Philip Payne, posted unretouched photos of herself posing in a bright blue bikini top ($39.95) and bottom ($29.95) from the brand on Instagram Wednesday.

“Hot girl summer or an indoor slay 🥶,” Lawrence captioned the shots. “If you tag us and #aerieReal in your photoshop free pics you can help raise funds for non profit @neda to help save lives from eating disorders 🙌.”

The body-positive activist further explained that Aerie will donate $1 per tagged post — and up to $100,000 total — to the National Eating Disorders Association.

“So get your real slay on for a great cause,” Lawrence urged.

Ever since announcing she was expecting, the blond beauty has shared plenty of updates with her nearly five million Instagram followers, opening up about everything from her workout struggles to maternity jeans.

Lawrence is due in March.
