Jessica Simpson's Baby Bump: The Sequel! It's been a while since the pregnant-again Fashion Star mentor, 32, has been photographed out and about. But on Wednesday (Feb. 6), Simpson was snapped in L.A. -- presumably headed to work out with her personal trainer.

The singer and fashion designer, who famously gained 50-plus pounds while carrying daughter Maxwell, 10 months, revealed a noticeably larger baby bump in a tight black workout top, which she paired with a black hoodie sweatshirt and green yoga pants.

Wearing little makeup and toting a bottle of water, the blonde star kept out the sun with huge sunglasses, wearing her hair in a loose ponytail. Although Simpson (who has worked with celeb trainer Harley Pasternak in the past) is evidently staying active during her surprise second pregnancy, she's taking a breaking from her Weight Watchers diet as she awaits the arrival of Maxwell's younger sibling.

The spokeswoman "will not be following the program during the pregnancy while her weight and well-being are monitored by her obstetrician, as is recommended for any woman during pregnancy," a Weight Watchers spokesperson said in a late December statement.

But the bubbly star (engaged to Eric Johnson since November 2010) plans to be more careful about her diet this go round. "I gained a lot more than doctors would recommend," she said on The Tonight Show last month. "I was really happy to be pregnant and I didn't ever step on the scale . . . I didn't realize you could gain that much weight that quickly."
