If you've watched any of the 2016 campaign... or the Republican National Convention... or, frankly, "The Apprentice," you probably know that Donald Trump has a bunch of kids. But how many? How old are they? What do they do?
Let's break it all down...
The Trump troupe
Real estate mogul Donald Trump has five kids: three with his first wife, the former Ivana Zelníčková, one with his second wife Marla Maples, and one with his current wife Melania Knauss.
The three you probably know
If you've ever watched "The Apprentice," you likely know the three children Donald Trump shares with his first wife, Ivana: Eric (left), Ivanka, and Donald Jr. They served as both advisers and boardroom judges on the popular show.
Trump's other leading lady
Donald Trump's leading lady, Melania, spoke at the opening night of the 2016 RNC. His other leading lady is his daughter, Ivanka...
Here, Donald embraces Ivanka (left) and Melania at the Met Gala in New York City on April 26, 2004.
Donald Trump's second oldest child, Ivanka, was born in 1981 and is now 34. A businesswoman, former model and fashion designer, Ivanka serves as Executive Vice President of Development and Acquisitions at The Trump Organization. She also has her own line of clothing, handbags and footwear.
Here, Ivanka and her father visit his Scottish golf course, Turnberry, on July 30, 2015 in Ayr, Scotland.
Ivanka - education
Ivanka spent two years at Georgetown University, before transferring to the Wharton School of the University of Pennsylvania... as Trumps are wont to do.
In October 2009, Ivanka married real estate developer Jared Kushner after about two years of dating. To marry Kushner, she converted to Judaism.
Of her new religion, she told Vogue: "It's been such a great life decision for me... I really find that with Judaism, it creates an amazing blueprint for family connectivity. From Friday to Saturday we don't do anything but hang out with one another. We don't make phone calls."
Ivanka and Jared Kushner now have a daughter and two sons together: Arabella Rose, Joseph Frederick and Theodore James (the youngest, born in March 2016).
She announced the news of Theodore's impending birth in a Facebook post, which read: "I have some very exciting news to share!! Check out this video and visit http://bit.ly/1WkLPSe for the super sweet (and hilarious!) outtakes."
Republican frontrunner Donald Trump's oldest son, Donald Trump Jr. (seen here at left), was born in 1977 and is currently 38. A businessman like his father, Donald Jr. is Executive Vice President of The Trump Organization.
Donald Trump Jr.
Following in his father's footsteps, Don Jr. attended the University of Pennsylvania for college. Upon graduation, he entered the family real estate business.
Donald Trump Jr.'s family
In November 2005, Donald Trump Jr. married model Vanessa Haydon. They now have five kids together.
Here, two of those children -- Kai Madison and Donald John III -- are pictured with their parents at Z100's Jingle Ball concert in New York City, December 11, 2015.
Donald Trump's third oldest child, Eric, was born in 1984 and is currently 32 years old. Like his older siblings, Ivanka and Donald Jr., Eric serves as an Executive Vice President at The Trump Organization. He also owns Trump Winery and runs The Eric Trump Foundation, a philanthropic group dedicated to raising money for the terminally ill children at St. Jude Children's Research Hospital.
Eric - education & controversy
Eric graduated from Georgetown University in 2006 with a degree in finance and management.
Several years later, he and his brother Donald Jr. came under fire for trophy hunting after photos surfaced of the two posing next to deceased elephants, leopards and crocodiles on a safari in Zimbabwe.
In November 2014, Eric Trump married longtime girlfriend Lara Yunaska at his father's Mar-a-Lago Club in Palm Beach, Florida. Ivanka's husband, Jared Kushner, officiated the wedding.
Lara Trump is a former personal trainer, avid equestrian, and works as a television producer on the CBS show "Inside Edition."
Donald Trump's only child with actress Marla Maples is Tiffany Trump, who was born in 1993, two months before her parents got married. She is now 22. Like her father and two of her older siblings, Tiffany went to college at UPenn.
Donald Trump and his wife Melania have one son together, named Barron, who was born in 2006 and is now 10 years old. Barron is fluent in both English and his mother's native Slovenian.
