Naya Rivera welcomed a baby boy [2] named Josey with husband Ryan Dorsey in September 2015, and now, just five months later, she's proudly showing off her toned physique. On Monday, the former Glee actress uploaded a snap of herself flaunting her enviable abs on Instagram, writing, "Yaaassss! Werk. It. Out. #fitmom @spingalnichelle." Since giving birth to Josey, Naya casually gave us a first look at her adorable little man [3] on Halloween, and two months later, she made her first post-baby red carpet appearance [4] at the March of Dimes Celebration of Babies luncheon in LA. See Naya's sexy snap above, and for more sultry photos, check out her hottest moments — so far [5]!
