Jessica Simpson is a mommy — again!

Jessica and fiancé Eric Johnson welcomed their second child, a baby boy named Ace Knute Johnson, her representative revealed Us Weekly.

Ace was born in Los Angeles via scheduled C-section on Sunday, June 30, the rep adds. "Ace Knute (pronounced Ka-nute) Johnson has arrived! Mom and baby are doing great," her rep said. "Jessica, Eric, and Maxwell are thrilled to welcome the new addition to their family." Ace's middle name honors Eric's Swedish paternal grandfather, Knute Johnson.

The singer, 32, and Eric, 33, are already parents to daughter Maxwell, nearly 14 months — which means they have two under two!

After about six months of dating, Jessica and Eric, a Yale grad and former NFL player, got engaged back in fall 2010, but were forced to postpone their nuptials twice due to her unexpected, back-to-back pregnancies. But a source recently revealed that they're hoping to finally tie the knot soon.

Back at Jessica's baby shower, a source said she "was telling friends she wanted to get married a few months after the baby is born. Jessica said, 'Let's have this wedding already before I get pregnant with another one!'"

We hope we hear wedding bells for the beautiful couple soon — before the couple has yet another unexpected bundle of joy!
