"I am so excited to be here. I cannot even contain myself," she told ET's Kevin Frazier while getting ready for the highly anticipated runway show backstage in Paris, France. "I have been a fan of the show since I was a kid. This is my second year but I do not think it will ever stop feeling like a dream come true. It is literally the greatest."
On Monday, Lady Gaga, who will be performing at the fashion show, shared a photo of herself posing with Gigi and Bella Hadid.
"Ok on a scale 1-10 how many men (or women) wish they were me right now," Gaga wrote on Instagram. "Caught in Babe Sandwich #vsfashionshow"
And it looks like Gigi is also a big fan of the "Joanne" singer.
"Gaga has been a great kind of big sister to me," Gigi said. "And has given me amazing advice, and I think she is such a beautiful person that is just set on spreading love everywhere she goes. I think that she is one of a kind, she is amazing."
Gigi also got emotional when talking about her sister, Bella. "It is a dangerous thing to ask about my sister because I am going to get emotional and I just got my makeup done," she said. "But, I am so proud of her. We watched the show together as kids, I feel like every sisters around the world that watch the show, dream about being in it together one day."
"For Bella and I to be the first sisters ever in the show together is just such a honor and we are just so excited to be here," she continued.
When asked how her mother, Yolanda Hadid, is dealing with her excitement, Gigi responded, "She is definitely losing her mind. I think that tonight she is a bit of a guest of honor being the mom of two in the show."
"I am pretty excited that she is here and that both my parents, my dad is here as well, get to see both Bella and I in the show, so it is going to be amazing," she added.
