President Donald Trump has become a grandfather for the 11th time. The 45th and 47th president of the United States' younger daughter Tiffany Trump and her husband Michael Boulos welcomed their first child, a son named Alexander Trump Boulos, on May 15. The president, who kicked off his visit to the Middle East earlier this week, mentioned his newborn grandchild while in Abu Dhabi on Friday.
"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 the president's eleventh grandchild. Donald is also a grandfather to son Donald Trump Jr.'s five kids—Kai, Donald III, Tristan, Spencer and Chloe; daughter Ivanka Trump's three kids—Arabella, Joseph and Theodore; and son Eric Trump's daughter Carolina and son Luke.
Tiffany is President Trump's fourth child and the only one he shares with his second wife, Marla Maples. Tiffany announced the arrival of her son, hours after giving birth on Thursday. Alongside a black-and-white photo of one of her baby boy's feet, the new mom wrote: "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 🩵👶🏻🩵."
Marla celebrated the birth of her first grandchild, commenting on her daughter's post: "✨🩵No greater joy in the world🩵✨ Michael and Tiffany this Gran Mar Mar loves you all so much!! You rocked it, my girl!"
Tiffany's father shared her 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."
At the time, a spokesperson for Tiffany confirmed to HOLA! USA that the first daughter was pregnant.
Ivanka Trump revealed last month that her sister was expecting a boy. Sharing pictures from the baby shower she planned for Tiffany, Ivanka wrote on Instagram: "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 ! 🕊️🩵🐇."
