"#MyGirls," the Michigan native -- who is returning to this network in four short days -- captioned the beautiful Instagram photograph above featuring the little ladies bonding and interacting. The curiosity in Nova's face and Carly's big grin -- what a special moment for Cate and Ty as well as Carly's parents Teresa and Brandon.
