The Finnish singer told Reveal: "My fiancée has a crush on Nicole – she has always loved her so much. When I first met her, she had Nicole's pictures on her phone… she was her screensaver on her laptop.
"I remember thinking, 'Oh no! Nicole is the most beautiful woman in the world.' No pressure, hey?"
While Saara is being mentored by judge Sharon Osbourne this year, fellow judge Nicole has always been a big fan. After Sharon sent Saara home at Six Chair Challenge, it was Nicole who brought Saara back to Judges' Houses as a wildcard.
Saara's now hoping Nicole may even agree to sing at her wedding!
She told us: "Before The X Factor, we were discussing who we would like to sing at our wedding, and we both agreed that Nicole would be so perfect. I'll have to ask her."

When Meri met Nicole for the first time, Saara shared a photo to Instagram with a caption telling fans dreams can come true.
"One of the best moments yesterday was when my fiancee @merisopanen met the love of her life @nicolescherzy," said Saara. "When I first met my girl she had Nicole's picture on her lock screen (that's how much she loves her .. And I was a bit jealous). And now she has this as her lock screen..
"Everything is possible. EVERYTHING! Even if you are from a small town from Finland. Remember that."
Saara and Meri became engaged last summer, after meeting when Meri messaged Saara via Facebook while Saara was competing on The Voice of Finland.
Saara told The Sun: "My girlfriend — fiancée now — watched the show, liked me a lot and sent me a fan message through Facebook. She wrote, 'I have never, ever sent a message like this to anybody, but I just had this intuition that I have to send this to you.
"I was like, 'That's so cute', and thought, 'What a nice-looking girl.' Then, after a year, she actually came to my concert and we met. We started talking and realised we just shared the same view of life and everything."
X Factor continues Saturday at 8pm on ITV.
