Kellie Martin gives child co-star some pointers

Kellie Martin

Kellie Martin has been acting since she lost her first tooth, and she's back in the camera lens for Hallmark Channel's "Smooch," airing Feb. 5.

This is a modern-day take on "The Frog Prince," where a young girl thinks she may have turned her lab experiment into a prince. Co-starring as the girl is Kiernan Shipka (Sally Draper on "Mad Men").

Martin says she lent some pointers to Kiernan about being a child actor. "I offered a little bit of advice. The first thing I said to her is that she has to go to Yale. And she agreed to do that, which is great. And actually I'm a fan of Kiernan's. My husband and I watch 'Mad Men' all the time, and way before I met her ... I would say, 'She's the most amazing young actress I have ever seen.' "
