Get ready for another Trump bump!

Ivanka Trump and her husband, New York Observer owner Jared Kushner, are expecting their second child, PEOPLE confirms.

The new addition will join daughter Arabella Rose, 20 months.

“Jared and I are so excited that Arabella will become a big sister this fall,” Trump Tweets. “Thanks for all your good wishes!”

Expanding the family will make life even more hectic for Ivanka, 31, given her top executive role at The Trump Organization. But she’s found a great balance as a working mother — though don’t use that term around her!

“I think the expression ‘working’ versus ‘non-working’ implies that a mother who stays home doesn’t work. It’s far more difficult than anything I do in the office,” she recently told Redbook.

“Every morning I’m so sad to leave Arabella. But it’s important for me to continue what I’m doing. It’s fulfilling to me, and I think it makes me a better mom when I’m home.”

Her father Donald, whom she judges alongside on Celebrity Apprentice, should be happy with another grandchild, too, as long as he has backup when babysitting.

“He takes her all the time — but with me,” Ivanka jokes. “He wouldn’t know what to do if she was crying or needed a diaper change.”
