Ivanka Trump Pregnant with Baby No. 2

Ivanka Trump and her husband Jared Kushner have announced this week that they are expecting this second child.

The couple have been married since 2009 and are already parents to Arabella Rose, 2-years-old.

"Jared and I are so excited that Arabella will become a big sister this fall," the heiress posted to Twitter. "Thanks for all your good wishes!"

Trump, 31, is the daughter of business magnate Donald Trump. The former model is also the executive vice president of development & acquisitions at The Trump Organization.

"I think the expression 'working' versus 'non-working' implies that a mother who stays at home doesn't work," Trump recently told Redbook. "It's far more difficult than anything I do in the office."

"Every morning I'm so sad to leave Arabella," the top Trump exec added. "But it's important to me to continue what I'm doing. It's fulfilling to me, and I think that it makes me a better mom when I'm home."

In other Trump family news, Dennis Rodman was recently fired from "Celebrity Apprentice" for spelling Donald's wife Melania's name incorrectly. Ivanka appears on the television series alongside her father.

Meanwhile, Trump joins a long list of other expectant mothers in Hollywood.

Jessica Simpson and her fiancé Eric Johnson are already parents to 1-year-old Maxwell, but are expecting baby number two later this year. Also, married actors Penelope Cruz and Javier Bardem are expecting their second child.
