Jessica Simpson has given birth to her second child with fiance, former NFL player Eric Johnson.

The couple welcomed their little baby boy, Ace Knute (pronounced Ka-nute), to the world last night.

The singer-turned-designer gave birth having planned a C-section for the delivery, CNN reports.

Jessica and Eric are said to be celebrating their new addition to the family with their one-year-old daughter, Maxwell Drew. 

The couple are now parents to Maxwell and Ace. 

The gnder was no surprise, however, as the singer-turned-designer accidentally let slip she was hvaing a little boy during an appearance on the Jimmy Kimmel Live show in March.

"It's a total different pregnancy. I just feel awful ... I've been vomiting," Jessica explained. "The crazy thing is, I never knew a wiener could actually make me nauseous."

"Well, I guess I just told the world I'm having a boy," she laughed.

Congratulations to Jess and Eric!
