Nearly two months after giving birth to son Ace Knute, Jessica Simpson is ready to share her baby boy with the world!

The 33-year-old, who welcomed the newest addition on June 30, is debuting her little one on the cover of Us Weekly, posing along with 15-month-old daughter Maxwell.

The mommy-of-two, who has been engaged to fiancé Eric Johnson since November 2010, seems to be happier than ever, telling the mag, “With two kids, we have our hands full, but every day is a new adventure. … It’s fun! I feel very at peace with being a mom.”

But will the cute couple, who had back-to-back babies, add more to their beautiful brood anytime soon?
