Ivanka Trump shared the first photo of her newborn son - Joseph Frederick Kushner - who was born on Monday.

In the photo, the 31-year-old wears no makeup and sits on the hospital bed as she holds the little baby.

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

This is the second child for Trump and her husband Jared Kushner. The couple, who wed in 2009, has a 2-year-old daughter named Arabella Rose Kushner.

Their first son was named after both Trump and Kushner's paternal grandfathers, whom she called inspirations.

"Jared's grandfather, Joseph, was a rock. His indomitable spirit, his sense of family, and his work ethic are the values we hope to hand down to our son," she wrote on her Tumblr page. "My grandfather, Frederick, was a builder not just of tens of thousands of homes throughout this city, but of a tight-knit family that honors to this day the traditions he established."

Baby Joseph's proud grandfather was the first to tweet the news of his birth.

"My beautiful daughter Ivanka just had a healthy baby boy. Jared and Ivanka are very proud!" Donald wrote on Monday. "Thanks to all for the wonderful congratulation sent to me on the birth of Ivanka's little boy - so nice!"
