Aww, Lucy Liu's little guy is getting so big! The star took to Instagram today to share an adorable photo of her and her mini-me son Rockwell, and we can't believe how much he already resembles his famous mom.

In the snap, the actress holds the 11-month-old as they smile for the camera while on the set of her hit TV series Elementary. Liu wears a blue button-up shirt, matching navy tie, and sunglasses in the picture, while Rockwell dons an animal print onesie in the same matching hues and his own set of tiny sunglasses. "Kicking off Season 5 with my mini @elementaryofficial @kickeepants," she captioned the too cute mother-son 'gram.

This is the first time we've gotten a good look at her boy in several months—she has only shared several photos of the sweet tyke since welcoming him via gestational carrier on Aug. 27, 2015, and we can't believe his first birthday is coming so soon.

Here's to more darling photos of Rockwell in the future.
