Tiffany Trump and husband Michael Boulos have welcomed their first child.

“Welcome to the world our sweet baby boy, Alexander Trump Boulos,” President Donald Trump’s youngest daughter announced on social media Thursday. “We love you beyond words!”

“Thank you for coming into our lives!” she added along with the black and white photo of her infant’s foot.

Tiffany’s mother, Marla Maples, celebrated the birth of her first grandchild in an Instagram comment, writing, “No greater joy in the world.”

“Michael and Tiffany this Gran Mar Mar loves you all so much!!” the comment continued. “You rocked it, my girl!”

Alexander’s arrival now makes the president a grandfather of 11.

Tiffany Trump and Boulos married at her father’s Mar-a-Lago resort in Palm Beach, Florida, in November 2022.

The president was the first person to make her pregnancy public, casually slipping the news in with a comment about his campaign surrogate Massad Boulos during a speech at the Detroit Economic Club.

“He happens to be the father of Tiffany’s husband, Michael, who’s a very exceptional young guy,” he said. “And she’s an exceptional young woman, so, and she’s going to have a baby. So that’s nice.”
