Ivanka, who works as the Executive Vice President of Development & Acquisitions at father Donald Trump's Trump Corporation, is already mom to daughter Arabella Rose, almost 2.
Ivanka once talked to UsWeekly.com about how she handles being a working mom. "I want to make sure I'm with my daughter when she needs me to be with her, but I also know that it's okay to go to the office when I'm working on a big deal then I'll make [family time] up on the weekend," she explained. "I try to think of parenthood as a marathon, not a sprint. I know that I have to do well at this by taking it one day at a time and not beating myself up too much over small things."
Ivanka and Kushner, Chairman of Observer Media Group, married in 2009.
“Celebrity Apprentice” mentor Ivanka Trump is expanding her family with husband Jared Kushner.
