“Not that I would have anything wrong with dating Cara but we’ve just always been best buds.
“I love Cara. She’s my sister and that never happened. For the record, I think being a lesbian would be fun and amazing.”
Jenner joked that being into women “would be fun and easier” because “men suck”.
She said: “By the way, I have nothing against having sex with Cara. I just have never had a desire to have sex with women. Never say never, right?”
Jenner, who is dating Jacob Elordi, clarified her relationship with Delevingne.
“We have been friends for a long time now – going on 11 or 12 years.
“She brought me under her wing – in a way – and made me feel really safe and welcome in the modelling world.”
Meanwhile, Delevingne previously identified as pansexual and has admitted it took her some time to figure out she’s a lesbian.
Appearing on the Louis Theroux Podcast this year, the model and actor said: “I think men are attractive.
“I think if you’re a lesbian, you can still find men attractive. I’ve never been in love with a man, so I think that classifies me as a lesbian.”
Delevingne, who is in a relationship with musician Minke and previously dated the likes of St Vincent, Amber Heard and Ashley Benson, admitted her sexuality took a while to figure out.
“Because it’s hard being gay. I think basic human instinct is to go for an easier path. But you can’t fight against who you are,” she said.
“I think there was always an element of people poking fun at it, which was fine because I did it too, people close to me. Because also, I guess I didn’t feel very seen for it, but I also know that my own personality is, I would take the p*** of myself, brush it under the rug, and not want to talk about it.
“But there’s a part deep down that you always want to feel understood a bit more, by straight people in your life who love you, who don’t understand it.”
