MASSACHUSETTS (WHDH) -- The day after Christmas, the biggest gift of all knocked on Karina Moreira's front door.
“I was just standing there like oh my god, and I just gave her a hug, an automatic hug, and it was really nice,” Moreira said.
Supermodel and fellow Brazilian Gisele Bundchen stopped by to visit Moreira.
Karina and Gisele met once before, two years ago at a Dana Farber event.
At the time, Karina was in the middle of chemotherapy treatments for bone cancer.
She was in remission, but the cancer came back and she started chemo again.
Like Gisele, this 15-year-old is a fashion aficionado.
She even has a blog, “Chic by Karina,” with plenty of how-to videos.
On Thursday morning, Karina and Gisele talked fashion, and shared make-up tips.
Gisele didn't just stop by to chat about make-up tips, she was at Karina's home to bring support and strength during a difficult time.
Gisele posted a photo of the two on her Instagram account writing:
"It was a pleasure to see you again @chicbykarina. You are a warrior, an inspiration of positivity and courage. I will be praying for you. Sending you love and light always."
“She says that you have to be really positive, and I actually agree with her, and I think that's very important,” Moreira said.
Karina is confident she'll beat cancer again, and after today's visit, she positive her friendship with Gisele is only just beginning.
