The singer and fiance Eric Johnson welcomed Ace Knute on Sunday.
Jessica Simpson is a mom two times over: She's given birth to another little one, this time a boy.
The baby, whose dad is Simpson's fiancé Eric Johnson, arrived Sunday in L.A. via a scheduled C-section, Us Weekly reports.
"Ace Knute (pronounced Ka-nute) Johnson has arrived!," her rep told the mag, noting that everyone in the family was "thrilled" about the new baby. "Mom and baby are doing great."

Little Ace's middle name is filling some pretty big shoes: It's there to honor Johnson's Swedish grandfather, Knute Johnson, People said. Of course there's that other famous Knute, Notre Dame's football-playing and -coaching Mr. Rockne, but hey, he pronounced it differently, right? But perhaps that's a nod to Dad's football history as well.
Ace joins big sis Maxwell Drew, who's just about 14 months old now. "Drew" is Jessica's mom's maiden name.
Simpson and Johnson have been engaged since November 2010.
