Jessica Simpson Is "Thrilled" To Meet Her Baby

Her secret is finally out, and now, pop-singer and fashion mogul Jessica Simpson just can't stop gushing about the baby she's expecting with fiancee Eric Johnson.

"We're both thrilled," Simpson, 31, tells Us Weekly in the latest issue, on newsstands now. "We can't wait to meet our baby!"

According to a friend of Jessica's, she hasn't suffered from any morning sickness, but she has been "really tired lately."

"She goes to bed super early now and gets up at 5:30 in the morning," the pal tells the magazine.

Perhaps that's partly because of her super-busy schedule. In addition to her shoe and clothing empire, valued at almost $1 billion, the mom-to-be also just launched a new skincare system, BeautyMint, is starring in NBC's upcoming reality show, Fashion Star, and even has a jewelry line with Zales in the works.

"The craziest thing is, she's still taking all her meetings -- in heels!" says a source.
