NEW YORK (AP) — Ming-Na Wen says her role as ace pilot and weapons expert Melinda May on "Agents of S.H.I.E.L.D." has convinced her children that she's cool. Wen says her son and her 14-year-old daughter, Michaela, are especially amazed because her kick-butt TV persona is so very different from the mom they know — a "girlie girl" who loves wearing sundresses. The 51-year-old actress says her kids' rave reviews are the best she could ask for.
