The 33-year-old stunner surprised 15-year-old Karina Xavier, who is battling bone cancer, with a visit on Thursday, Dec. 26.
A fashion blogger who, like Gisele, originally hails from Brazil, Xavier posts style tips on her website ChicByKarina.com and has even shared her future aspirations of becoming a makeup artist someday on her Facebook page.
So the surprise visit from Bündchen was undoubtedly a dream come true for the young fashionista, who shared photos on social media while gushing over the quality time she spent with the supermodel.
"From the moment you surprised me, until the moment you left, I was so shocked for you being here with me!" Karina captioned a photo on her Facebook page of the pair. "Thank you so much for taking time off of your day to come visit me and spend some time with me! Also thank you for your kind words and your very meaningful gifts! You are a great person and you will continue inspiring me I love you @giseleofficial And to my followers: Stay tuned for something special on my blog!!! I'm so happy!!!!!!"
Karina also shared a photo of herself doing Mrs. Tom Brady's makeup, uploading the pic with a number of OMG emojis.
"Guess whose makeup I did today!!!" she wrote.
But the humble teen wasn't the only one touched by impromptu get-together. The mother of two also took to Instagram to share her own kind words for Karina.
"You are warrior, an inspiration of positivity and courage. I will be praying for you. Sending you love and light always," she posted in both English and Portuguese.
Couldn't agree more—clearly, the model's inner beauty matches the outer.
