Jessica Simpson and her fiance Eric Johnson (II)'s baby boy has arrived. Their bundle of joy was born on Sunday, June 30, in Los Angeles via scheduled C-section. They are already parents to an adorable daughter, 14-month-old Maxwell.

"Ace Knute (pronounced Ka-nute) Johnson has arrived! Mom and baby are doing great. Jessica, Eric and Maxwell are thrilled to welcome the new addition to their family," Jessica's representative told Us Weekly. The representative added that the baby boy's middle name honored Eric's Swedish paternal grandfather, Knute Johnson.

Jessica got pregnant with her second child just seven months after Maxwell's arrival. They confirmed the pregnancy via Twitter on Christmas Day. The 32-year-old singer shared a picture of Maxwell sitting on sand atop the words, "Big Sis."

The "Fashion Star" mentor originally wanted to keep her second child's sex a secret, but she made a slip during an appearance on "Jimmy Kimmel Live!". "The crazy thing is I never knew a wiener could make me nauseous," she jokingly said. The mother of one added, "Well, I guess I just told the world that I'm having a boy!"

Speaking to Ellen DeGeneres, the "I Wanna Love You Forever" singer revealed that her second pregnancy was different from her first experience. "This pregnancy is the complete opposite. Like with Maxwell, I felt amazing. Like I could do everything, eat everything. Do whatever I wanted. I had a lot of energy. This time around, I'm like exhausted," she said in March.
