Mom's The Word! First Look At Jessica Simpson's Baby Bump Number 2

Jessica Simpson's  second pregnancy within a year didn't stay secret for long and these first photos of her new bump prove she wouldn't have been able to stay mum anyway!

Heading to the gym and holding a bottle of water Wednesday, the engaged star's newly bulging belly was impossible to miss, and RadarOnline.com has the first photos of the mom showing why she's doubly happy this year.

The Weight Watchers spokeswoman is engaged to Eric Johnson and they are the parents of-9-month-old  daughter, Maxwell.

Speaking with Jay Leno last month, the 32-year-old said she "didn't ever step on the scale" the first time  around, and as a result, gained "a lot more than doctors would recommend.

"I didn't really make any healthy good decisions," added Jessica, who went on to lose  50 pounds before she got pregnant a second time.

As we previously reported, Jessica, who's expecting a boy, will resume her Weight Watchers diet after she gives birth.

She also joked with Leno that she was looking forward to marrying Johnson but was unable to plan a wedding because he keeps getting her pregnant!
