Baby Maxwell Drew is only two weeks old, but her mom Jessica Simpson is already cashing in on her new venture into motherhood.

The pop star and flourishing designer announced plans today for her latest collection, aptly named Jessica Simpson Maternity. Simpson's new line, available at Destination Maternity, Motherhood Maternity and Macy's stores this fall,  includes "breezy, everyday pieces aimed at the modern mom-to-be who wants to maintain her fashion edge throughout her pregnancy," according to a press release on Destination Maternity's website.

The clothes, which include printed tops, maxi dresses, jackets, blazers, sweaters, knits and denim, will have a vintage 1970s feel and start at just $36. Photos from the collection are posted on People's website.

Simpson's maternity wear marks the 24th line in the Jessica Simpson Collection. The singer is well on her way to earning $1 billion by year's end just from her fashion empire alone.

Meanwhile, the new mother is adding to her coffers with a reported $3 million deal from Weight Watchers to lose the baby weight.

According to Women's Wear Daily, she sold the baby's first photos to People magazine for a cool $800,000.
