Jessica Simpson is one proud momma! She recently shared an adorable photo of baby Ace Knute Johnson.

According to Access Hollywood, Simpson posted a picture of Ace on Twitter on Saturday, October 5th. The black and white snapshot was captioned, “three months.”

The precious photo shows Simpson smiling with son Ace in her arms. Both mom and baby look happy and healthy as they look straight into the camera.

The 33-year-old designer gave birth to baby Ace via c-section on June 30th of this year in Los Angeles. Simpson and her fiance Eric Johnson shared the news of their baby boy with US Magazine, saying, “With two kids, we have our hands full, but every day is a new adventure. It’s fun! I feel very at peace with being a mom.”

Ace is Simpson and Johnson’s second child together. They also share daughter Maxwell, who is 17 months.

The new mom has also been hard at work to get her body back after giving birth. Simpson initially signed a $4 million deal with Weight Watchers in August. Six months into the deal, Simpson announced that she was expecting baby number two.

Simpson also recently teased Twitter followers that she may be getting back into the music business. She tweeted, “I need to make music” a couple of weeks ago.
