He is the new "Roseanne" character getting lots of notice. 9-year-old grandson mark played by Ames Mcnamara. Do you feel like you're a boy or a girl? A boy. So what's up with the girls' clothes? This just feels like me. I like colors that pop. And while mark creates mixed peoplings in the conner household. You hear that, honey. My grandson's nails are wet. Producers say he's just a kid. The kid is 9 years old. He's too young to lime girls or boys. Who knows what he likes. Stop it. He is a lot of fun and he's very fashionable. And is surrounded by love. If things get rough I put pants and a t-shirt in your backpack and you know what, you're still going to be you. No, I won't. I'm fine, mom. And the young man who plays mark, Ames Mcnamara, joins us now. Welcome to "Gma," Ames. Thanks so much for having me. I like that jacket. Thank you. So what's your take on mark? Mark is just a Normal kid. He likes to do art. He likes playing basketball. And just wearing girls' clothes is just a small part of mark. When they told you about mark what did they tell you about how to play him and what did you bring to it? So, they didn't really tell me because I play mark as a Normal kid and that's who he is and the girls' clothes are just a small part of it. Likes to express himself. Yeah. Did you know what a gender nonconformity was before the show. No, I was aware certain people like to wear clothes from the opposite gender and knew a kid like that in a play I did but I wasn't aware of it. How much fun are you having. I'm having so much fun. Tell me about Roseanne. She is a great actress but what I love about her most she treats me like a fellow actor. If a joke was funny and they took it out she would be like, Ames, that joke is funny. Why did they take it out. This is your first show. It's been a great experience and everyone has been so welcoming to me. What had you done before that.
