Ireland Baldwin writes emotional letter to newborn half-sister

Ireland posted a letter full of advice to Carmen on her blog just hours after her birth. "You have entered the world! Welcome! We have all been anticipating your arrival! By we, I mean a lot of people. Girl, you haven't even met them, but there are a ton of people who care about you," she posted. The blonde model warned her newborn sister about drinking, smoking marijuana, dating, trusting the wrong people, and assured her that she will always be there for her. Ireland also addressed her own parents' bitter split and how much it hurt her growing up.

"Remember your parents will always love you. As a kid, you forget that sometimes. When they are screaming about this and bickering about that. It hurts. Grown ups yell. I don't know why, but they do. No matter what your mom or Dad says or does, simply remember that they love you. Never forget it. "I love you, Carmen. You have been born into one crazy family. You are both lucky and cursed at the same time," Ireland added.
