Congratulations go out to Ivanka Trump and husband Jared Kushner who yesterday (Oct. 14) welcomed their second child into the world, a son.

Trump, 31, tweeted the festive news last night:

And her proud father, The Donald, broke the news to his followers as well:

The couple's firstborn, daughter Arabella Rose, is 2.

The gorgeous entrepreneur covers the October-November issue of Fit Pregnancy magazine in a high-slit orange frock, the cover of which she unveiled on Instagram a month ago. She tells the magazine of her and Kushner's decision to keep the baby's sex a secret until birth, explaining: "I'm superstitious. 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."

Kushner and Trump have been married since 2009.

UPDATE: Trump later revealed the name of her newborn on her Tumblr blog: Joseph Frederick Kushner, "named after each of our paternal grandfathers, both master builders of their generation and inspiring patriarchs of their families."
