Ivanka Trump is pregnant with her third child.

The 33-year-old businesswoman and former model (and daughter of Donald Trump) announced Thursday morning that she's expecting a baby with Jared Kushner, 34, her husband of nearly six years. They already have two children: daughter Arabella, 4, and son Joseph, who turns 2 in October.

She revealed the news Thursday in a post on Facebook that included a cute video featuring her children. The kids hold up numbers and say "Baby One!" and "Baby Two!" before mom holds up a No. 3 over her belly and says "Baby Three!"

I have some very exciting news to share!! Check out this video and visit for the super sweet (and hilarious!) outtakes:
