Ivanka Trump is now a proud mom of two! The 31-year-old "Celebrity Apprentice" mentor gave birth to a baby boy on Monday Oct. 14.
"We just welcomed a beautiful & healthy son into the world. Jared, Arabella and I couldn't be happier!" Ivanka tweeted.
Trump and husband Jared Kushner, the chairman of Observer Media Group, are already parents to Arabella, 2. The couple, who wed in 2009, announced in April that they were expecting their second child. "Jared and I and are so excited that Arabella will become a big sister this fall," she tweeted at the time. "Thanks for all your good wishes!"
Trump decided to keep the gender of her second child a secret from the public. "I'm superstitious," she told Fit Pregnancy in October. "I don't like to tell people, but I don't have the discipline to keep it a surprise. There are so many variables in motherhood that, those I can control, I like to."
Fortunately, Trump told the magazine that her second pregnancy was going well at six months along. "I feel amazing," she said at the time. "Thankfully, I never experienced morning sickness, but I did get a wave of fatigue that started at week 15 and went through week 17. I can't complain, because it dissipates so quickly, but waking up exhausted is not a fun feeling."
Trump, who works as the Executive Vice President of Development & Acquisitions at father Donald Trump's Trump Corporation, spoke exclusively to Us Weekly in May about how she juggles her career and motherhood.
"If I'm working on a big deal and need to be in the office, I'm in the office. If Arabella needs me, I better be home and accessible and available," she explained to Us. "Parenting is something you don't get right every day, but you try to get right as many days as possible. Ultimately it's a marathon. Time matters and being a consistently accessible, supportive parent is important."
