Former President Donald Trump announced during a speech at the Detroit Economic Club that his daughter Tiffany Trump, 30, is expecting her first child with husband Michael Boulos, 27. Tiffany married Boulos at Mar-a-Lago in November 2022, and the couple has maintained a relatively private life. Boulos, the heir to a Nigerian conglomerate, proposed to Tiffany in the White House Rose Garden with a $1.2 million engagement ring. The announcement marks the upcoming birth of Donald Trump's 11th grandchild. Both Tiffany and Michael have yet to publicly comment on the pregnancy news. The announcement was part of Trump's campaign stop in Michigan, where he acknowledged Michael's father, Massad Boulos, in the audience.
