Jessica Simpson Gives Birth to a Boy, Ace

And baby makes four!

Jessica Simpson gave birth to a boy on Sunday, Us Weekly reports. He is the second child for the singer-designer and her NFL-player fiance, Eric Johnson, who welcomed daughter Maxwell into the world on May 1, 2012.

"Ace Knute (pronounced Ka-nute) Johnson has arrived! Mom and baby are doing great," Simpson's rep tells Us, confirming that she delivered via a scheduled C-section in Los Angeles. "Jessica, Eric and Maxwell are thrilled to welcome the new addition to their family."

Simpson, 32, and Johnson, 33, got engaged in fall 2010, but postponed their wedding twice due to the unexpected pregnancies.

Simpson confirmed the sex of her son in March during an appearance on Jimmy Kimmel Live. "The crazy thing is I never knew a wiener could make me nauseous," she joked of her morning sickness. After realizing what she had just said, Simpson added, "Well, I guess I just told the world that I'm having a boy!"
