Eric Trump and his wife, Lara, are expecting their first child — and President Trump is on cloud nine.

The couple is expecting a boy, who is due in September and will be the president’s ninth grandchild.

“We found out on my birthday, which was pretty cool,” said Eric, 33, People reported.

Lara, 33, a former “Inside Edition” producer, said she’s in her second trimester and feeling great.

“I was exhausted in the beginning,” she said. “It surprised me, because I’m a very active person, and until the fatigue hit, I didn’t believe it would actually happen to me. It really affected me. But I’m feeling really good now.”

The couple is now busy thinking of a good name for the power progeny.

“We really loved the name Charlie, but we’d already named our dog that, so it’s out,” Eric said. “We sort of screwed ourselves over there,” added Lara, who is now involved in animal charities.

She said she’s not nervous about being a first-time mom.

“I knew I always wanted kids someday,” she told the celebrity news outlet. “Eric’s going to be an amazing dad. The nieces and nephews love hanging with him. He’s the cool uncle. He’s watched ‘Frozen’ many times.”

The couple dated for six years before tying the knot in 2014 at Mara-a-Lago, now dubbed the president’s Winter White House.

They were happy to leak the very real news of the pregnancy because the secret was hard to keep under wraps.

“Eric’s dad was so excited that we were worried he’d blurt it out at a press conference,” Lara joked.

Eric’s brother Don Jr. has five kids with his wife, Vanessa, while sis Ivanka has three with her hubby, senior White House adviser Jared Kushner.

In less cheerful news Monday, TMZ reported that one of Don Jr. and Vanessa’s kids — Tristan, 5 — broke his leg Sunday during a skiing trip to Aspen with his and Ivanka’s families.

The Secret Service accompanied him from the slopes to a hospital, the gossip site reported.
