Jessica Simpson gives birth to second child, baby boy Ace Knute Johnson

Jessica Simpson has given birth to her second child, baby boy Ace Knute Johnson.

Ace Knute Johnson was born on Sunday, June 30, in Los Angeles, after Jessica, 32, had a scheduled C-section.

A rep told UsWeekly: “Ace Knute [pronounced Ka-nute] Johnson has arrived! Mom and baby are doing great.”

Jessica Simpson and her 33-year-old fiancé Eric Johnson are already parents to daughter Maxwell who is almost 14-months-old.

The couple’s rep said: “Jessica, Eric and Maxwell are thrilled to welcome the new addition to their family.”

Ace’s middle name honors dad Eric Johnson’s Swedish paternal grandfather, Knute Johnson, and is pronounced “Ka-nute”.

Jessica Simpson accidentally revealed she and her fiancé, a former NFL player and Yale grad, were having a son during a TV interview with Jimmy Kimmel in March.

In typical Jessica Simpson fashion the news slipped out accidentally.

“The crazy thing is I never knew a wiener could make me nauseous,” she told the chat show host.

Jessica Simpson then laughed off the on-air mistake, saying: “Well I guess I just told the world that I’m having a boy!”

“I can’t believe I just did that, that was not planned,” she said good-naturedly.

Later Jessica Simpson said: “I just did it so crude, I feel awful!”

But she didn’t seem too worried by the gaff, as she later tweeted: “Accidental announcement tonight on @jimmykimmel.”

A source close to Jessica Simpson and Eric Johnson, who got engaged in 2010, previously revealed that they were keen to tie the knot shortly after the birth of their son.

But the blonde beauty fears she may fall pregnant again and be forced to cancel her wedding plans a third time, having previously nixed their nuptials because of the unexpected baby news.

In March, Jessica Simpson said humorously of her situation: “I keep planning on getting married but I keep getting knocked up.”

A source said: “[Jessica] was telling friends she wanted to get married a few months after the baby is born.”
