Ivanka Trump has a new nephew: Alexander Trump Boulos! The Women Who Work author congratulated her sister Tiffany Trump and brother-in-law Michael Boulos on becoming parents, the day after the birth of their first child.
"Welcome to the world sweet Alexander ! 🩵Congratulations Tiff and Michael on this precious blessing ! Love you ! 💕💕💕," Ivanka wrote on Instagram. The first daughter, 43, commented on the post her younger sister, 31, shared on Thursday announcing Alexander's arrival.
Tiffany posted on May 15 a black-and-white photo of one of her newborn's feet, which she captioned: "Welcome to the world our sweet baby boy, Alexander Trump Boulos. We love you beyond words! Thank you for coming into our lives! 5.15.2025 🩵👶🏻🩵."
In the comments, Tiffany's mother, Marla Maples, also celebrated Alexander's arrival, writing: "✨🩵No greater joy in the world🩵✨ Michael and Tiffany this Gran Mar Mar loves you all so much!! You rocked it, my girl!"
While in Abu Dhabi on Friday, President Donald Trump, who kicked off his visit to the Middle East earlier this week, mentioned his newborn grandchild. "It's been a tremendous time and now it's time to go back home. My daughter had a baby. I'm gonna go back home and see that little baby," the president said.
Alexander is President Trump's eleventh grandchild. The 45th and 47th president of the United States is also a grandfather to son Donald Trump Jr.'s five kids—Kai, Donald III, Tristan, Spencer and Chloe; daughter Ivanka's three kids—Arabella, Joseph and Theodore; and son Eric Trump's daughter Carolina and son Luke.
Donald shared Tiffany's pregnancy news back in October during remarks at the Detroit Economic Club. While recognizing his son-in-law Michael's father, Massad Boulos, Donald said, "He happens to be the father of Tiffany’s husband, Michael, who’s a very exceptional young guy. And she’s an exceptional young woman."
He added, "And she’s going to have a baby, so that’s nice."
A spokesperson for Tiffany confirmed to HOLA! USA at the time that the first daughter was pregnant.
Ivanka revealed last month that her sister was expecting a boy. Alongside photos from the baby shower she planned for Tiffany, Ivanka penned, "This Sunday, I had so much fun planning and hosting a Peter Rabbit-themed baby shower for my sweet sister Tiffany! We showered her with love and had the best time celebrating her and baby-to-be! Every detail was inspired by Beatrix Potter’s world — from bunny tails to garden treats — to celebrate the little boy she’s about to welcome into her life. It was the sweetest day — filled with so much love, laughter, and excitement for everything ahead."
She continued, "Tiff, you’re going to be the most wonderful mama. Your baby boy is already so loved — and so lucky to have you! Love you ! 🕊️🩵🐇."
