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.
