Alexander Trump Boulos turned 4 months old ahead of his parents' trip to the United Kingdom. Tiffany Trump commemorated the monthly milestone with a belated post on her Instagram Story on Monday, Sept. 22. The mom of one shared an adorable new photo of her baby boy that showed the 45th and 47th president of the United States' grandson, dressed in a blue collared knit jumpsuit, on a lamb play mat with a sign resting on his stomach that read: "four months old."
The first daughter, 31, and her husband Michael Boulos welcomed their first child, Alexander, on May 15, 2025. He is the American president's 11th grandchild. Alexander turned 4 months old the day before his parents departed the White House for the UK.
Tiffany and Michael accompanied her dad President Donald Trump and stepmom, First Lady Melania Trump, on their second state visit to the United Kingdom. The couple joined the president and first lady at the state banquet on Sept. 17. Michael walked in the royal procession with the Princess of Wales, whom he sat next to during the dinner at Windsor Castle. Meanwhile, Tiffany entered with Apple CEO Tim Cook.
Proud mom Marla Maples shared footage of her daughter Tiffany at the dinner on her Instagram Story, writing: "My girl and Michael at Windsor Castle." She added, "And I get to be with Alexander 😁."
The next day, Marla posted a carousel, including pictures and footage from the state banquet, which she captioned: "Last night my daughter Tiffany and her wonderful husband, Michael, looked radiant at the State Dinner, photographed with Prince William and Princess Catherine. I couldn’t be prouder of the grace and kindness that shine through her smile ✨ I happily stayed home with our sweet grandson, soaking up every precious moment. 👑 🌟💫."
Tiffany and Michael returned to D.C. on Sept. 18. Days later, the president's younger daughter shared pictures from the night of the state banquet on her Instagram. "It was an honor to attend the State Banquet at Windsor Castle 🇺🇸🇬🇧," Tiffany wrote alongside the images. "My deepest thanks to Their Majesties King Charles III and Queen Camilla, and to Their Royal Highnesses The Prince and Princess of Wales, for such a memorable evening. ❤️✨💙."
