Congrats to Ivanka Trump and her hubby Jared Kushner. The Donald's daughter gave birth to her second child, a son, on Monday, Oct. 14. The happy mom, 31, tweeted the news just hours after the birth, a sign of the digital times we live in!

Trump, who designs jewelry and serves as a boardroom judge on 'Celebrity Apprentice,' shared her good news about her son rather quickly. Unfortunately for us, since we like to gawk at babies and their names, Trump did not reveal the boy's moniker nor did she share a pic or other pertinent details…yet.

Big sister Arabella Rose was born in July 2011.

Below is Ivanka's post-birth tweet as well as grandpa Donald Trump's tweet.

You can feel the pride leaping out of both their tweets. The Trump family continues to expand.

Congrats again to Ivanka, Jared, Arabella and the Donald.
