Jessica Simpson is a mommy ... again!
The 32-year-old singer-turned-fashion designer gave birth to a baby boy named Ace Knute Johnson on June 30, reports Us Weekly.
"Ace Knute (pronounced Ka-nute) Johnson has arrived! Mom and baby are doing great," a rep for the singer told the magazine. "Jessica, Eric and Maxwell are thrilled to welcome the new addition to their family."
This is her second child with fiance Eric Johnson, 33. The couple welcomed daughter Maxwell Drew on May 1, 2012.
Simpson lost 60 pounds on Weight Watchers after giving birth to Maxwell and continued to follow her diet while pregnant with her little boy.
"This time around, I'm exhausted, eating Tums, that's my snack of choice," she told DeGeneres. "The first pregnancy I let loose and kind of ate everything that I wanted to eat and I just really enjoyed it. This time around I think because I was doing Weight Watchers and I felt super healthy. I'm not really craving as much and I know how hard it is to get off so I'm trying to make healthier, wiser decisions."
