Ivanka Trump has announced she is expecting.

"I have been wanting to share some amazing news with you all for some time," Trump wrote on her Twitter on Friday. "I'm pregnant!"

The 29-year-old The Apprentice star and husband Jared Kushner -- who married in October 2009 and began dating in 2007 -- have been celebrating the good news.

"Jared and I couldn't be more excited," Trump added.

Trump and the New York Observer owner briefly split in July 2008 but eventually reconciled and announced their engagement in July 2009. The happy couple wed only three months later in a ceremony held at the Trump National Golf Club in New Jersey.

The Celebrity Apprentice's fourth edition will premiere on Sunday, March 6 at 9PM ET/PT.
