Donald Trump Jr. and his wife Vanessa have welcomed their fourth child into the world.
The businessman, who has appeared on his father's reality series "The Apprentice," announced that his wife had given birth to a son Sunday on his Twitter account.
"It's a BOY!!! @MrsVanessaTrump and baby are doing great," the proud father tweeted.
Trump, 34, works alongside his siblings as an Executive Vice President at The Trump Organization, a company conglomerate based out of New York that deals with hotels, golf courses, and other business ventures. Trump Jr. married model Vanessa Haydon on November 12, 2005 at the Mar-A-Lago estate in Palm Beach, Fla. They announced the birth of their first child, a daughter named Kai Madison, in 2007.
The couple also has two other sons, Donald Trump III who was born in 2009, and Tristian Milos who was born in October of last year. Trump's followers joked on Twitter about how long it would be until their most recent son would follow in the family footsteps.
"Congrats. How soon until he's sitting in the boardroom?" one Twitter follower joked. "2 maybe 3 weeks," Trump responded jokingly. The businessman added that for now however, the house was likely to resemble a "zoo."
"Yea it should be a zoo but very fun!!!" he said in response to another Twitter user.
Trump's brother also added congratulatory wishes for his brother and his wife, adding that he was happy to meet the new addition on Vanessa Trump's Twitter.
"Congrats to @DonaldJTrumpJr & @MrsVanessaTrump on the birth of another perfect baby boy. It was great to go meet the little man today!" Erich Trump wrote.
All of the Trump children are under the age of five, Trump's likely reason for considering it a "zoo."
