The 32-year-old model has walked in the luxury lingerie company's annual fashion show 13 times, as has Alessandra Ambrosio.
Adriana is stunned to still be strutting her stuff each year and enjoys mentoring the label's new faces.
"I'm definitely the grandma," she laughed to vogue.co.uk. "I first walked in the show in 2000, but I was working with the brand even before that actually. My first show, Stephanie Seymour and Karen Mulder were in it too - and it is amazing to have done the show for so long… I love the new girls, though. Cara [Delevingne] is so cool. I love the girls that they choose, they are always super nice, really excited. It's just the most fun job."
There are many benefits to being a model for so long, some of which effect Adriana's personal life. She enjoys speedy shopping sprees as she instantly knows whether an item is going to flatter her curves.
"I never try anything on, actually," she explained. "After so long wearing so many different styles, I can look at something and know if it will suit me; even sunglasses. It's great - I just say, I don't need to try them, I'll take these! It's the same with Victoria's Secret, the designers know what we all like to wear - the colours and shapes we like - and they really listen to us."
Adriana is looking forward to spending Christmas with her husband Marko Jarić and their daughters Valentina, four, and 15-month-old Sienna.
Valentina can't wait for the big day, with her mom taking steps to ensure she doesn't get carried away beforehand.
"She's a bit afraid of Santa," Adriana giggled. "But she is definitely excited about the presents! We're having to work hard to stop her opening them all before the day."
