Jessica Simpson may have started losing the baby weight, but one thing's here to stay: Her ginormous boobs!

Jess and fiance Eric Johnson touched down at Los Angeles International Airport on Tuesday night, and the 32-year-old singer/actress flaunted her cleavage in a low-cut maxi dress. Jess made her first post-baby appearance on Katie Couric's new show on Monday, and she chatted about losing the weight, motherhood and her wedding plans.

Jess also revealed that she's 10 pounds away from her pre-baby weight, and she shared some info about her diet and work outs with Us Weekly. After waking up to feed 4-month-old daughter Maxwell, Jess usually starts her day with a flatbread sandwich with egg whites, peppers and fat-free cheddar, and after taking a late morning walk, she snacks on fruit.

Four times a week Jess has a 45-minute session with trainer Harley Pasternak, where she does cardio, circuits, arms, legs and abs. What's next? "I make lunch my biggest meal to keep me full through the day," she says. One of Jess' go-to plates is spinach salad with 4 ounces of chicken satay and pear, and for an afternoon snack she'll often drink a smoothie. Jess added that dinner is usually a lighter meal consisting of fish (4 ounces of halibut or tilapia) with veggies, and every once in a while she'll indulge and have a Skinny Cow chocolate truffle bar.

But seriously ... we can't stop staring!
