“My snuggle bug…” she captioned the pic in which her adorable 6-month-old son is sitting in a swing.

Simpson, who also has an 18-month-old daughter Maxwell Drew with her fiancé Eric Johnson, recently described what it’s like being a mother of two.

“With two kids, we have our hands full, but every day is a new adventure,” she said. “It’s fun! I feel very at peace with being a mom.”

Back in December, the 33-year-old singer revealed her secret about losing weight after giving birth to son Ace.

“With both kids I’m running up and down my stairs a million times,” she told USA Today. “Kids can keep your metabolism going.”
