Who Is Donald Trump's Other Daughter? Meet Pop Singer Tiffany Trump

Mogul Donald Trump's five children joined him on stage last month when he announced his presidential run, including his 21-year-old daughter, Tiffany Trump. Tiffany is not as widely known as her ambitious older siblings, all three of whom appeared on their father's reality show "The Apprentice." But she has gradually tried to get her share of the spotlight.

Tiffany is the second youngest heir, and the only child of Donald Trump and his second ex-wife actress Marla Maples, who divorced when she was five. After the split, Maples, 51, moved her daughter across the country from the infamous Trump boardroom to Calabasas, California. With her siblings in New York, Tiffany has admitted that her Southern California upbringing has made her feel different from them.

"Since I have grown up on the West Coast, I’m definitely different from all of them growing up on the East Coast," Tiffany told the Daily Mail.

Maples has said that Donald has provided for her financially, but Tiffany has admitted in interviews that she was mainly raised by her mother.

"My mom and I have always been very close. I think she did raise me as a single mom," Tiffany told The Oprah Winfrey Show. "Growing up, we were always together and I know my friends -- everyone at home -- is like, 'Wow, you guys have a really good relationship.' "

While a high school senior, Tiffany launched her music career with the release of her pop single "Like a Bird" in February 2011 on Amazon. But instead of pursuing music full time, Tiffany graduated and enrolled in her father's alma mater, the University of Pennsylvania's Wharton School of Business.

Since relocating to the East Coast for school, Tiffany has been spotted out more in the New York social scene. Nightlife photos have shown her at clubs with friends such as Harry and Peter Brandt, the sons of model Stephanie Seymour, and Gaia Matisse, the great-great-grandaughter of artist Henri Matisse. On her Instagram account, she has been posting photos partying in the Hamptons this summer at swanky spots such as The Surf Lodge in Montauk and Beautique in Southhampton, while her father hits the campaign trail.

It is unclear if Tiffany will follow her two older brothers Donald Jr., 35, and Eric, 29, and sister Ivanka, 31, into the business world alongside her father. She has expressed interest in fashion, landing a high-profile internship at Vogue two summers ago. Her sister, Ivanka, who has been featured in photospreads in the magazine, told the Daily Mail that her younger sister had the opportunity as an intern to grab lunch with editor-in-chief Anna Wintour. This summer, Tiffany has been busy interning at Italian fashion group Aeffe's New York office, where she instagrammed herself with the caption, "Control the tempo and you can usually control the game #internlife."

Recently, she showed support for her father's presidential candidacy, posting photos from his campaign launch to her Instagram. "Congrats @realdonaldtrump on your announcement! So proud of you! #MakeAmericaGreatAgain," she wrote.
