Eric Trump took to Twitter on Monday to announce that he and wife Lara are expecting a baby boy due in September.
The baby will be the couple’s first.
“We found out on my birthday, which was pretty cool,” the 33-year-old son of the President of the United States told People magazine.
Lara Trump, also 33, said she experienced fatigue and exhaustion early on in her pregnancy but is now feeling great.
“It really affected me. But I’m feeling really good now,” she told People.
She added that her father in law, President Donald Trump, was “so excited” to find out she was expecting “that we were worried he’d blurt it out at a press conference.”
The president retweeted his son's post on Monday, adding, "Congratulations Eric & Lara. Very proud and happy for the two of you!"
It will be the ninth grandchild for President Trump.
Eric, 33, and his brother Don Jr. are now running the Trump Organization after the president said he cut ties with his business to take office.
