On Thursday, the supermodel, who welcomed her first child — a baby boy named Levi Joseph — with husband Joshua Kushner in March, showed off her post-baby body via a gym selfie on her Instagram Story.

Posing in front of a mirror, Kloss, 29, bared her toned physique while dressed in a green sports bra and black leggings. The Project Runway host explained in text written over the photo that she "worked hard" for her "abs."

In a video shared to her Instagram Story at the time, Kloss cuddled little Levi before giving him a kiss on the head.

While only three months old, Levi has had his own share of milestone moments. In June, Kloss took her baby to Disney World for the first time. Kloss shared photos from the family trip to Instagram, writing: "Levi's first visit to the Happiest Place on Earth and mommy's 1253th."

For the special occasion, Levi was dressed in a grey outfit, patterned with Micky Mouse faces. Kloss had on some Disney duds of her own — specifically a pair of limited edition mouse ears she designed for her collaboration with the Disney Parks Designer Collection.
