Hello, baby Alexander! The newest Trump family addition — Alexander Trump Boulos — made his “public” debut a day after his famous grandfather's birthday celebration.

New mom Tiffany Trump posted photos of her one-month-old baby boy, tagging husband Michael Boulos, in a Father’s Day Instagram Story.

The holiday, which is always the third Sunday in June, was June 15 this year, a day after President Donald Trump turned 79. He and other members of the Trump family attended his much-anticipated military parade in Washington, D.C., on June 14. It was the same day as the 250th anniversary of the U.S. Army — and more than 1,000 nationwide “No Kings” protests, with 80 in Florida and some down the road from Donald Trump’s private club, Mar-a-Lago in Palm Beach.

Tiffany Trump wished her billionaire husband a “Happy 1st Father’s Day, my love. We love you so much @michaelboulos Thank you for being the best daddy to our little boy.”

In her post, there’s a photo of Boulos holding baby Alexander along with pics of the couple with their stroller along White House grounds.

Tiffany Trump’s Instagram photos were the first public debut of Donald Trump’s 11th grandchild. The baby was not with his parents at the VIP family box at the military parade, but with her view of the opening ceremonies as well as photos of her and her dad, wishing him a happy birthday.

Below is more information about Tiffany Trump, her new baby Alexander Trump Boulos and her father, the president.

Who is Tiffany Trump? When did Tiffany Trump give birth to Donald’s grandson?

Tiffany Trump, only child of President Donald Trump and Marla Maples, and her billionaire husband Michael Boulos, welcomed their son at 4:44 a.m. Thursday, May 15, 2025, days after Mother’s Day.

Donald Trump turned 79 on Saturday, June 14, 2025, which was the same day as the U.S. Army's 250th Birthday Parade in Washington, D.C. It was also the day before Father's Day, which was June 15 this year.

Tiffany Trump's baby boy, with billionaire husband Michael Boulos, is the 11th grandchild of Donald Trump and the first for Maples, a former model and second ex-wife to the commander-in-chief. Donald Trump and Maples were married from 1993 to 1999. (His first marriage to Ivana Trump − with whom he has three children: Donald Trump Jr., Ivanka Trump and Eric Trump − was from 1977 to 1990. He married current wife, First Lady Melania Trump, in 2005. They have one child together, their son Barron Trump.)

Tiffany Trump, the 31-year-old mom and former model married the 27-year-old businessman Boulos in 2022 at Mar-a-Lago, Donald Trump's private club and home in Palm Beach, Florida.

Throughout her pregnancy, Tiffany Trump shared photos of the "Trump baby bump" and gave her social media followers a peek at the Peter Rabbit-themed baby shower hosted by her older sister, Ivanka Trump.

On the day of baby Alexander Trump Boulos' birth, the new mom shared a photo of her hand holding his tiny foot and captioned the image: "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"

Several celebrities, Trump family members and well-known public figures posted congratulatory comments, including Elon Musk's mother, Bettina Anderson and Kimberly Guilfoyle, ex-fiancee of Tiffany Trump's brother, Donald Trump Jr.

Proud grandmother, Marla Maples or "Grand Mar-Mar" as she has called herself, has posted updates about baby Boulos, particularly his "angel number" birth time of 4:44. But the former "Dancing With the Stars" contestant has not shared any photos of Alexander online.

Donald Trump's military parade, which spanned six blocks near the National Mall, occurred Saturday, June 14, in the heart of Washington, D.C.
