Stuart recently took to Instagram to post a sweet picture of herself and long-time boyfriend, Robbie Streeting, which she captioned, "Happy birthday to my beautiful boyfriend."
And now the world is taking note of the man who has managed to capture Stuart's heart.
He was her first kiss and the adorable moment happened on her 18th birthday.
According to Woman's Day, Streeting recently turned 20, and he also has special needs. We don't know exactly how long the couple have been together, but according to the publication, their Facebook pages suggest they've been together for at least two years — their sweet pictures go pretty far back on Stuart's Instagram, too.
Even though she has a demanding career that requires her to jet across the globe, it's evident that Stuart makes time for the special man in her life.
And his birthday is not the only special moment they've shared together.
The pair also shares a love of dance, and they are both part of Bust A Move Dance classes.
Stuart is inspiring others that being different is beautiful, too — and Streeting appears to be her biggest supporter.
Earlier this year Stuart's mother, Rosanne Stuart, gave an interview to the Huffington Post, revealing when Madeline feels the most beautiful.
"All the time. Maddy has a beautiful soul, so she feels good about herself and she always feels beautiful. She does like getting dressed up in her prettiest dress and going to the movies with her boyfriend, Robbie, and gets all cute and shy when he tells her she looks beautiful," Rosanne confessed.
Stuart and Streeting are clearly smitten, and it's beautiful to see.
