Lucy Liu shared an adorable photo of her baby boy, Rockwell, on Instagram on Monday. In the snapshot, the 2-month-old flashes a sweet smile while wearing a toy-car-covered onesie. Lucy captioned the photo simply, "Mood #Rockwell." The Elementary star welcomed her beautiful son via surrogate [2] back in August, and since then, she's only shared one other snap of the little tot — a picture that shows her holding a bundled-up Rockwell [3] while he sleeps. Take a look at Rockwell's precious face above, then check out all the celebrity families you should be following on Instagram [4].
