Celebrity Apprentice star Ivanka Trump is pregnant again with her second child.

Trump, 31, and her husband, businessman Jared Kushner, are expected to welcome a second child this fall. Baby no. 2 will be younger sibling to the couple's first child, 20-month old Arabella Rose.

A source told New York Post Page Six column that "Ivanka is starting to tell friends and family about her pregnancy."

Ivanka's second child will be Donald's sixth grandchild. In addition to Ivanka's daughter Arabella Rose, the billionaire's son, Donald Trump, Jr. has four children with his wife.

"The Donald" however, can expect an even bigger brood of grandchildren- Ivanka recently told Forbes Life that she would "love to have three children, maybe four."

Kushner oversees the Observer Media Group which includes The Observer newspaper. Ivanka converted to Judaism before the couple married on Oct. 25, 2009.

Ivanka wears many hats- in addition to joining her brothers at the judges' table in the boardroom on Celebrity Apprentice, she is the Executive Vice President of Development and Acquisitions at the Trump Organization where she oversees the company's real estate, hotel management and acquisitions.

She is also an entrepreneur with a successful jewelry and fashion business brands, Ivanka Trump Fine Jewelry and the Ivanka Trump Lifestyle Collection which includes fragrance, footwear, handbags, outerwear and eyewear.
