Donald Trump a Grandpa Again as Don Jr. Welcomes a "Beautiful" Son

This is the third child for the businessman and his wife, Vanessa—and he's got a fancy name!

Anyone up for The Celebrity Apprentice: Grandkids edition?

Donald Trump became a grandfather for the fourth time when eldest son Donald Jr. and wife Vanessa welcomed their third child together early Sunday morning.

"8lb 4oz born 2:59 am Sun oct 2. Mom and baby doing great! He can't wait 2 meet his big brother & sister," Don Jr. tweeted today.

But while there was no big, fancy birth announcement (not today, anyway), did the real estate empire scion get a big, fancy name?

Yes, he did.

The little tycoon's royal name is Tristan Milos Trump. Rather romantic, don't you think?

"I am delighted that Don and Vanessa have a beautiful new member of their growing family," grandpa Trump said in a statement.

The couple are also parents to daughter Kai, 4, and Donald III, 2.

"Upon meeting Tristan for the first time Donnie (aka D3) to Mom 'Momma is that a real one?'" Don Jr. tweeted.

(Oh, and because this family mixes business with pleasure, Trump Jr. also retweeted this from his dad: "@THeCelebrityApprentice cast is set—the best we've ever had. Shooting starts in 2 weeks—airs in February.")
