Inside Kai Trump's lavish 19th birthday party as mom Vanessa shares emotional tribute

"Happy Birthday to my firstborn, Kai. I am beyond proud of you and all that you have accomplished. Watching you graduate from high school and begin this new chapter into adulthood is one of the proudest moments of my life," she wrote in the caption.

"You have worked so hard to get where you are today, and it truly shows. You have grown into such an amazing young woman, smart, strong, kind, and determined."

She continued: "From excelling in school to being an incredible role model for your siblings and everyone around you, you continue to inspire me every single day. I love you with all my heart, and today is all about celebrating you."

Vanessa began with a photo from Kai's prom, where she shared a moment with her mom before heading to the event. She then posted a selfie of the pair on a car ride, followed by a picture with her arm wrapped around her daughter on the golfing green.

Kai then shared several snaps from her special day, which saw her posing beside giant balloons in the shape of birthday cakes. She wore a white tank top paired with a white ruffled skirt and sneakers, and took a moment to pose with her friends and her father, Donald Trump Jr. 

The menu for Kai's party included buffalo wings, basil pesto pasta, tacos, and a pink cake featuring a cascading opening decorated in gold. 

The YouTuber is incredibly close to her mother, as the eldest of Vanessa's five children with her ex, Donald Jr. "Happy Mother's Day to the best Mom I could ever ask for," Kai wrote on social media on Sunday. "I'm so thankful and lucky to have you in my life. Thank you for always supporting me and loving your five kids. You are such an amazing Mom, and we are all so lucky to have you. I appreciate you more than anything."

Vanessa's former sister-in-law, Ivanka Trump, revealed to People that the mother of five was a "Wonder Woman" when it came to wrangling her children. 

"My sister-in-law Vanessa is a machine," Ivanka said. "She can take all of [my children] and not even notice. She has five children, and she's Wonder Woman to me."

"She can be taking care of them all simultaneously, each pulling on her and have direct meaningful connections with each of them at one time. It's remarkable." 

Meanwhile, Donald Jr. shared several throwback photos of his daughter on her birthday, and captioned the carousel: "Happy birthday to my absolute favorite 19-year-old child. @kaitrumpgolfer I love you and continue to be amazed at the woman you're becoming."
