Ivanka Trump is pregnant with her third child.

The daughter of US Presidential candidate Donald Trump and her husband Jared Kushner, 34, will add to their brood - which already includes four-year-old Arabella and 23-month-old Joseph - early next year.

Ivanka told PEOPLE: ''Jared and I are thrilled to announce that we'll be welcoming baby number 3 to our family early next year. It's an incredible blessing. We feel so grateful - and so excited!''

The 33-year-old businesswoman also announced the news on her Facebook page, with a cute video featuring her two children.

And she posted a message on her website, detailing their excitement.

She said: ''I couldn't be more thrilled to share the news with you that I am expecting. Arabella and Joseph are both incredibly excited to have a new sibling on the way (of course, Arabella desperately wants a baby girl, and Joseph hopes it's a boy!), and I wanted them to join me in making the announcement.''

She added: ''I consider myself incredibly fortunate to have a career that I am deeply passionate about, but, at the end of the day, it's my family that is at the centre of my life- and to be adding another baby to our family is a tremendous blessing. Jared and I are so thankful, and so excited!''
