Rachel Zoe gave birth to her infant son, Kaius Jagger, less than two months ago, and the new mom is already back to her pre-baby figure. When the famously rail-thin fashion stylist stepped out in Beverly Hills on February 10, all signs of her previously protruding baby bump had completely disappeared.

Little Kaius made his debut on December 22, and his slender mama seemed to pop back to her former size almost instantly. Granted, in these photos her midsection is being covered by a giant coat, but one look at her slim legs and it seems pretty clear that Rachel doesn’t have an extra ounce of fat on her.

The Zoe Report creator was out shopping with her eldest son, Skylar, age 2. Rachel, 42, has been married to her kids’ father, Rodger Berman, for more than 22 years.

With New York Fashion Week in full force, Rachel is very busy with work right now, but she’s still making motherhood a top priority. On February 11, the designer posted an Instagram photo of her and Kaius snuggling in bed.

“This is how @msjordanjohnson of @rachelzoestudio and I watch the Oscar de la Renta show when No wifi at the office #ODLRLIVE #RZFW #STUNNING” she wrote. As Rachel watches the show from her laptop, Kaius rests peacefully on her chest. Aww. How cute is that? Sleep tight, little one!
