Jessica Simpson and fiance Eric Johnson welcomed their second child, a baby boy named Ace Knute Johnson Sunday.

Reports indicated that the 32-year-old singer gave birth to a healthy baby boy in Los Angeles at Cedars-Sinai Medical Center, the same hospital Kim Kardashian came birth to baby North West two weeks ago. 

Simpson delivered the baby via a scheduled C-section.

"Ace Knute (pronounced Ka-nute) Johnson has arrived! Mom and baby are doing great," the singer's rep confirmed to Us Weekly.  "Jessica, Eric and Maxwell are thrilled to welcome the new addition to their family."

The newborn joins big sister, Maxwell, 1, to the Johnson household.

Simpson's second pregnancy to Ace was revealed in November 2012, just seven months after Maxwell's birth. 

The actress confirmed the sex of her baby back in March.

"The crazy thing is I never knew a wiener could make me nauseous," she said. "Well, I guess I just told the world that I'm having a boy!"

Simpson and Johnson got engaged in fall 2010, but were forced to postpone their wedding twice due to back-to-back pregnancies.

Enstars reported earlier that back in April during Jessica's baby shower, sources said she wants to get married a few months after the baby is born.

Jessica was reportedly heard saying, "Let's have this wedding already before I get pregnant with another one!'" a source said.

She joked with late-night host, Jay Leno earlier in her pregnancy that she and Johnson 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 said of Johnson in January.

Just two weeks ago, Simpson attended the wedding of Beverly Hills' interior decorator Kathryn Sykora's wedding on June 15.

The Fashion Star mentor was a bridesmaid in the wedding as she flaunted her baby bump in a tight black dress. 

"Jessica seemed in great spirits despite looking like she was ready to burst," a source told E! News, "thought she was definitely touching her belly quite a bit and moving around slowly."
