The actress, 27, made the revelation during an Instagram Q&A, where she revealed the correct pronunciation of her surname, Cülcüloğlu.
She said: "It's pronounced as jul-jul-aw-loo, jul-jul-aw-loo."
The reality star also opened up about her baby plans with her Love Island boyfriend, Davide Sanclimenti, also 27.
A fan asked: "How many kids do you want when you are older with Davide?"
"I'd say two," she replied with a winking emoji.
The revelations came after Ekin-Su announced on Lorraine that they are moving in together, with Davide moving from Manchester where he is currently based.
"Basically we've decided that we are moving in together, confirmed, it's official!" she said.
"And we are thinking perhaps end of September to possibly move into Essex, where I'm from. Davide's not been to Essex and I feel like it's so nice because it's near London, it's easy to travel to, bit of countryside but then also a bit of that edginess to it as well."
Ekin-Su also opened up about the colossal amount of support she and Davide have received since winning Love Island by a landslide.
"It's been absolutely overwhelming," she said.
"You know, it's such a successful show, I didn't think I'd find the love of my life and ended up finding the perfect man. Not just the perfect body."
She continued: "I'd had no idea I had this love and the support and I just want to be thankful to everyone. Even my haters, I love them as well."
However, while the couple might be happily loved up now, as viewers of the show know, their journey was far from plain sailing, and Ekin-Su explained that she once needed medical intervention as a result of a panic attack.
"In Casa Amor, obviously there was a moment... I don't know... I'm gonna say this, medics came," she revealed. "I was having a mini panic attack because I was like, 'oh no what's Davide doing in Casa Amor? Is he with someone else?"
"And the medics were like, 'Ekin it's fine, just relax, what's meant to be will be'. And you know, it all worked."
However, reality TV fans won't have to wait long to see the fiery couple on their screens again either, as they announced that they will be having their own show just days after leaving villa.
As reported by Marie Claire, Davide said: The Big Breakfast: "I can tell you this. We are going on a road trip to Italy and Turkey, for one week in Italy and one week in Turkey. We are going to be on ITV2, and it’s going to be like our own programme."
