It's a girl for Alec and Hilaria Baldwin.
The 29-year-old yoga instructor gave birth to the couple's first child, whom they named Carmen Gabriela, on Friday.
Alec's first daughter, 17-year-old Ireland Baldwin, welcomed her little sister with an open letter onTumblr filled with advice and warnings.
She advised her new sibling to “enjoy your child hood and your teenage years” by not growing up too fast, and not to let other people define her beauty. She also jumped the gun a bit and shared tips about getting drunk. (“Don’t be that girl that gets wasted at parties and crawls on bathroom floors. It ain’t cute.”)
Ireland ended the letter by telling the newborn, "You are both lucky and cursed at the same time. We are going to have so fun much fun together. I can’t wait to meet you soon. I promise you I will always be there for you no matter what! Never forget!"
