Big congrats to Jessica Simpson and her fiance Eric Johnson—they've given birth to a baby boy named Ace Knute Johnson, Us Weekly confirms.

Baby Ace was born today in Los Angeles via a scheduled C-section.
"Ace Knute (pronounced Ka-nute) Johnson has arrived! Mom and baby are doing great," her rep tells Us. "Jessica, Eric and Maxwell are thrilled to welcome the new addition to their family."
Baby Ace joins big sister Maxwell, who is just over a year old.
