Donald Trump Jr. and Wife Vanessa Expecting Baby No. 4

Business mogul announced that he will be expanding his family

The Trump brood continues to grow.

Donald Trump Jr. announced on Twitter today that his family is expecting another bundle of joy, "Well, Vanessa & I have some good news we are expecting baby num 4 in the fall!!! Kai, Donnie, & Tristan can't wait!"

Trump married model wife Vanessa Haydon in November 2005. They currently have three children together, daughter Kai, 4, and sons Donald, 3, and Tristan, 6 months.

The real estate developer was recently making headlines after photos of himself hunting elephants, crocodiles and other animals while on safari in Zimbabwe last year were released.

At least now we know that not only does he hunt, but he mates as well.

Congratulations!
