Donald Trump's granddaughter Kai Trump celebrates major life milestone as her next steps are revealed

Congratulations are reportedly in order for Donald Trump's eldest granddaughter, who just hit a major life milestone.

Not only did Kai Trump - the daughter of Don Jr and his ex-wife Vanessa Trump - celebrate her 19th birthday last week (12 May), but she also recently graduated from high school.

The youngster had previously attended The Benjamin School in Palm Beach, Florida, but has now set her sights on college.

According to Trump family insiders, Kai plans to attend the University of Miami when September rolls around, where she'll compete on the collegiate golf team alongside her studies.

Speaking to PEOPLE, one source based in Jupiter, Florida, described the YouTuber as being 'extremely focused on golf', adding: "She has demonstrated the discipline to continue with it and go as far as she can.

"She is a good player. I think she will improve a great deal under the right coaching."

UoM's women's golf team finished in 10th at this year's ACC Championships, an achievement Kai reportedly hoped to contribute to in 2027.

"Kai was impressed with the team in Miami and is excited about going to school there," the insider continued.

Apparently, the prospective student has 'grown up' playing golf - especially since moving from New York to the Sunshine State aged 13 - with her Republican grandfather himself being an avid golfer, as well as the owner of over 20 courses.

In a video shared last month, 79-year-old Trump gushed about his granddaughter: "I just wanna say that I play a lot of golf with Kai and she’s a fantastic golfer."

He added: "She's a scratch player, which is amazing. I think some day in the not-too-distant future, she’s gonna be much better than scratch. But she’s doing really well, and she wins a lot of matches.

"And some day she’ll be able to beat her grandfather, but I’m not sure when that’ll be - it might be a long time."

It isn't just granddad Donald that has shown Kai the ropes, but several of the family's celebrity friends - including mum Vanessa's new partner.

Vanessa, 48, went public with Tiger Woods - widely regarded as one of the greatest golfers of all time - back in March of last year.

Not long after her mother's new romance was revealed, Kai claimed 50-year-old Woods had given her advice before her LPGA Tour debut.

"He is the best golfer in the entire world, and he's an even better person," she gushed at the time. "He told me to go out there, have fun, go with the flow."
