Showing the world that her little lady is growing up, Jessica Simpson tweeted a picture of her daughter Maxwell Drew on Saturday (August 17).

Simply captioned "Maxwell is crazy beautiful," the adorable shot shows the toddler sitting by a window in a pink tee shirt with a cupcake on it as she holds on to a favorite blanket.

The 15-month-old bares a stunning resemblance to her "Employee of the Month" actress mother, as well as her football player father Eric Johnson.

Maxwell isn't the only kid in the household these days, as baby brother Ace Knute, who is said to look like his sis, was born back in June.
