How cute!

Jessica Simpson covers the new issue of Us Weekly with her daughter Maxwell and her two-month-old son Ace, and this is the first time we've gotten a peek at the little guy!

Jess was photographed at her Hidden Hills home two weeks ago for the shoot, and while she looks great here, she opens up about her dealing with "hurtful" comments about her weight. On a lighter note, she says, "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."

However, don't look for her to go the same route as Heidi Klum -- Simpson isn't planning on having more kids anytime soon! "Pregnancy is a lot. It was hard to do two so close together," she tells the mag. "I have this huge sense of accomplishment, and I feel in my heart that I'm done. But obviously, accidents do happen!"
