Donald Trump's elusive youngest daughter Tiffany has proved that Ivanka isn't the only blonde beauty in the family.

The 21-year-old University of Pennsylvania student looked stunning as she lounged by the pool in a white one-piece swimsuit with cut-outs during her recent trip to the Trump's Mar-A-Lago club in Palm Beach, Florida.

Tiffany chronicled her spring break on Instagram earlier this week while she enjoyed her time off from the family's Ivy League alma mater.

Tiffany, who is Donald's daughter with his second ex-wife Marla Maples, grew up in California, where she remained shielded from the spotlight.

But it doesn't look like the young heiress will remain hidden for much longer.

Tiffany shared multiple photos vacation photos of herself with her nearly 16,000 Instagram followers.

One picture shows her sporting a body-hugging one-piece and over-sized black sunglasses as she sits with her legs crossed on a towel covered lawn chair.

'Just had to restart my heart,' one commenter wrote. Someone else added: 'What a beauty.'

Another snapshot captures her frolicking in the Atlantic Ocean in a cheeky black bikini.

But before she was able to escape Philadelphia's frigid winter weather, she had to pull a few all-nighters to study for her exams.

In a selfie she posted to Instagram last week, she can be seen wearing knit cap, a cozy scarf, and black puffy coat with fur hood.

While Tiffany is a dedicated student who is focused on school, she also has a passion for music.

In 2011, she released her single Like A Bird on Amazon.

'I love music; it's always been very dear to me,' she said that year.

'It's more of a hobby right now, but we’ll see in a couple of years if I actually want to take it to the next level as a professional level.'
