Move over real estate — Donald Trump may not have time for business now that he’ll be busy taking care of four grandchildren!

The toupee-wearing mogul’s son and fellow Apprentice star, Donald Trump Jr., welcomed baby #4 into the Trump family on Sunday.

“It's a BOY!!!” Donald tweeted after his wife, handbag designer Vanessa Trump, gave birth to the little boy yesterday. “@MrsVanessaTrump and baby are doing great.”

While the couple hasn’t released the child’s name yet, the tiny bundle of joy will join older siblings 5-year-old Kai, 3-year-old Donald III, and Tristan, who is 11 months old.

Congratulations to the happy family!
