Evans is certainly enamored with her little boys, posting a nostalgic photo of Jace as a newborn alongside a newborn photo of Kaiser. "Jace the day I took him home on the left," she wrote alongside the comparison pictures, "Baby Kai on the right."

While baby Kaiser has been getting quite a bit of attention, Evans made sure her eldest son didn't feel left out. "This little man will always be my buddy," tweeted Evans yesterday evening, "Had one-one-one time with Jace!" Evans included some photos of her and Jace making silly faces together in the car. Aware of her critics and their scrutiny, Evans added that they weren't wearing seat belts because the car was parked.
