Jessica Simpson Baby [PHOTOS]: Look Back at the Pregnant Star's Maternity Style
Jessica Simpson gave birth to Ace Knute Johnson, via a scheduled C-section Sunday in Los Angeles.
This is the second child for the 32-year-old singer/TV personality and her fiance, former NFL player Eric Johnson. Ace has a big sister, 1-year-old Maxwell Drew.
In December, Simpson confirmed pregnancy rumors by tweeting a photo of her daughter, Maxwell, above the words, "BIG SIS."
The two children will be very close in age: Simpson gave birth to Maxwell just last May.

Us Weekly also broke news in February that Simpson planned on naming her child "Ace." Ace's middle name honors dad Eric's Swedish paternal grandfather, Knute Johnson.
Simpson, who told Jimmy Kimmel in March that this time around, she's felt very sick. It was then that she revealed the baby's gender.
"The crazy thing is, I never knew a wiener could actually make me nauseous," she said. "Well I guess I just told the world that I'm having a boy!"
A month later, Simpson feted her little boy with a sweet Tom Sawyer-themed baby shower.
At the April 14 baby shower, she "was telling friends she wanted to get married a few months after the baby is born," the source told Us Weekly.
"Jessica said, 'Let's have this wedding already before I get pregnant with another one!'"
