Jessica Simpson Pats Pregnant Belly on Stroll With Eric Johnson

Pregnant Jessica Simpson and Eric Johnson get ready for baby No. 2 in Beverly Hills on June 13, 2013.

It's almost time! The birth of Jessica Simpson's second baby is fast approaching, but she's not just sitting at home waiting to pop. On Thursday, June 13, the pregnant Fashion Star mentor stepped out in Beverly Hills looking casual but chic in a summer frock and flats.

Rocking a short, black lace dress with an olive-green jacket and sandals, the 32-year-old singer laid a protective hand on top of her growing baby bump as she and fiance Eric Johnson strolled through a parking garage. Her blonde hair was pulled back into a casual, braided updo, and she carried an oversized orange purse on one arm. Johnson, clad in jeans and a T-shirt, walked a few steps ahead of her.

As Us Weekly exclusively revealed in late May, Simpson hopes to tie the knot with her beau soon after welcoming baby No. 2. (The couple are already parents to daughter Maxwell, 13 months.)

During her Apr. 14 baby shower, Simpson "was telling friends she wanted to get married a few months after the baby is born," a source told Us of the Weight Watchers spokeswoman. "Jessica said, 'Let's have this wedding already before I get pregnant with another one!'"

Early on in her pregnancy, the star joked with Jay Leno that she and her fiance were "doing it very backwards" by having kids before getting married. "We've had two different wedding dates, but he keeps knocking me up," she quipped of Johnson, to whom she has been engaged since 2010.

"I'll just keep my legs crossed, I guess, this time," she continued. "Apparently it was part of God's plan for my life."
