Ashlee Simpson is fittingly celebrating a "magical human" with a 'gram of a special mother-son moment.

The 32-year-old, who rang in her son Bronx's eighth birthday on Sunday, took to Instagram to send some social media love and well wishes his way in the form of a sweet birthday message and a candid throwback photo where Bronx looks like her mini-me.

The musician, who shares the tot with ex-husband Pete Wentz, began her message, "8 years ago today I had this magical human."

"You are everything and more than I could have ever dreamed of!!" Mom continued in the caption. "Happy birthday, Bronx."

Simpson's heartwarming 'gram depicts the ecstatic mom of two, dressed in a striped sweater and knit hat, crouching down by a homemade lemonade stand while bubbles swirl in the foreground. The toddler, who looks just like mom with a mop of curly blonde hair, stands while dressed in a skeleton-print hoodie as he appears to sing to Simpson.

Looks like little Bronx is definitely his mama's boy!
