Wednesday on "TheTalk@Home" Justin Hartley opens up about "This Is Us" and his character [Kevin Pearson] being a father of twins. "I love the development of the character for sure. I think that's unbelievable. If you look at where we found him in the pilot...we then find him now. He's a man. He's like a full grown man. It took him awhile to get there, but he got there." Hartley adds, "Now they're going to give me twins. I guess, so now, I'm getting a double dose. So it's kind of cool. I'll take it back to the Manny days." On Kevin 'having babies' with Madison Simons [played by Caitin Thompson], Hartley spills, "I think it was a good decision to sort of develop her character like that." He adds, "I'm excited to get into the storyline with her and kind of see where it goes. I actually know where it goes, and it's really interesting and fun and I think something that hasn't been done on television before."
