The couple chose to share the news via social media. "We welcome with love, Joseph Frederick Kushner," Ivanka Trump wrote on her Tumblr page Tuesday, along with a photo of her new son, born Monday night.

We just welcomed a beautiful & healthy son into the world. Jared, Arabella and I couldn't be happier!" she tweeted.

Proud multi-millionaire grandfather Donald Trump previously said he was thrilled to have welcomed another member to his family.

The boy's name Joseph Frederick Kushner got his name "after each of our paternal grandfathers, both master builders of their generation and inspiring patriarchs of their families," Ivanka wrote on her Tumblr blog.

"Both men set the standards that have been passed down through the generations and which we hope to impart upon Joseph and Arabella," wrote Ivanka, 31. "They created a legacy for our family that inspires our careers as well as our love and respect for one another. We are honored to name our son after these two distinguished men."

Ivanka Trump and Jared Kushner welcomed Arabella Rose, their daughter, in July 2011.  Ivanka Trump and Kushner, 32 - principal owner of Kushner Properties and chairman of Observer Media Group - married in 2009.
