Kai Trump has raised some eyebrows after posting a video to TikTok celebrating her final night as a 17-year-old. President Donald Trump's granddaughter posted a clip of her and three of her friends lip-syncing the song 'Promiscuous' by Nelly Furtado and Timbaland while they donned black dresses and high heels. Kai has had an active social media presence ever since her appearance at the Republican National Convention last year. 📷 KaiTrump/TikTok #shorts #trump #kaitrump #selfie #birthday #news Daily Mail Website: https://www.dailymail.co.uk Daily Mail Facebook: https://facebook.com/dailymail Daily Mail IG: https://instagram.com/dailymail Daily Mail Snap: https://snapchat.com/discover/Daily-Ma...
