Kai Trump has posted publicly for the first time since details about her mom's romance with Tiger Woods emerged. The president's granddaughter took to YouTube, where she revealed she is on a first-name basis with 'Tiger'. 'Hi guys, I know I have not posted a YouTube video in a very long time and it's just because I had some stuff come up,' Kai, 17, told her viewers. 'I had to focus more on my actual golf and school work,' she explained. Kai shared the video as an update about her experience playing at the Genesis Open alongside Rory McIlRoy. She then went to talk about the San Diego tournament and the organizations helping put on the event where her familiarity with Woods was evident. 'They have two foundations that support it, TGR - that's Tiger's foundation, and California Rise,' Kai explained. It comes after DailyMail.com revealed her mom Vanessa Trump's secret relationship with golfer Woods. Vanessa, 47, who is Donald Trump Jr.'s ex-wife and Woods, 49, both live in Florida, and have been together since Thanksgiving. They are quickly becoming golf's new power couple and were seen arriving together at a tournament on February 16. Four sources confirmed to DailyMail.com that the pair are an item. They live 20 minutes apart in the wealthy southern Florida enclave of Palm Beach and were spotted together at a golf tournament last month. Vanessa's eldest daughter Kai, 17, and Woods' children Charlie, 16, and Sam, 17, all attend the $38,595-a-year The Benjamin School. Other members of the Trump family, including all five of Vanessa and Don Jr.'s children, are aware they are an item, one source said. Kai and Wood's son Charlie Woods are both aspiring golfers with sights set on turning professional. Both are slated to compete against each other in a junior tournament next week. Their families appear to have become increasingly close. Last month, at the PGA Tour's Genesis Invitational at Torrey Pines in California, they were pictured arriving together. Kai, who committed to playing golf at the University of Miami next year, wore an outfit from Woods' clothing line. In February, Vanessa took Kai to watch a round of the TGL, the golf league created by Woods and Rory McIlroy. Meanwhile, President Trump met up with Woods for a round of golf last month. After his divorce from Vanessa, Don Jr. had a long-term relationship and engagement with former Fox News host Kimberly Guilfoyle, who is now President Trump's Ambassador to Greece. But in September, DailyMail.com exclusively published images of Don Jr. in southern Florida with West Palm Beach socialite Bettina Anderson. By December, Don and Guilfoyle's relationship was over and he began publicly dating Anderson after his father's 2024 election win.
