Meghan Markle made her public debut as a mom on Wednesday when she posed for pics inside Windsor Castle alongside husband Prince Harry and their newborn son. "It's magic. It's pretty amazing!" Markle said while sporting a sleeveless coat dress and showing a bit of a remaining baby bump. "I have the two best guys in the world, so I'm really happy." She added that their still-unnamed son has "sweetest temperament...He's calm, he's just been a dream." Harry--who held their swaddled son throughout the photo-op--added, "Parenting is amazing. It’s only been what, two and a half days, three days, but we’re just so thrilled to have our own little bundle of joy. We have to spend some precious time with him as he slowly starts to grow up.”USA Today notes that Queen Elizabeth II is also scheduled to meet her great-grandson sometime on Wednesday.
