Maralee Nichols is three months postpartum and showing off her rockin’ bod.

The fitness model and former mistress of Tristan Thompson took to her Instagram Story on March 1 to show off her gains in the gym.

She wore a black sports bra and bright pink spandex pants.

Maralee welcomed her first child, a baby boy, late last year.

Thompson is the father, but he’s reportedly a non-existent father.

She captioned one photo of her backside to the mirror, “I eat 5-6 times a day & drink a gallon of water.”

In another Story on March 2, she shared a photo of two Beyond Breakfast Sausage packages.

“I cook breakfast every morning. Super important part of my diet is to eat in the morning. I don’t eat any pork. I love these @beyondmeat breakfast sausages they are delicious 😋,” she wrote.

Last month, the new mom announced the name of her little one, Theo Thompson.
