Cara Delevingne cancels on Museum of Sex event at last minute

After drunkenly nearly falling off a stage at a starry Halloween party — model Cara Delevingne had organizers scrambling at another event.

We hear Delevingne canceled an appearance at Monday’s opening of the exhibition “Reclaiming & Making: Art, Desire, Violence,” for the Museum of Sex on Fifth Avenue, after the invitations and press releases went out touting her involvement.

“She was meant to promote her partnership with sex-tech brand Lora DiCarlo” (which she co-owns) said an insider, “as well as bring attention to the important works in the new exhibition.”

Delevingne said earlier this year of becoming a co-owner and creative advisor of the Lora DiCarlo line: “My friends are like, ‘I know what I’m getting for Christmas.’ You know, I was sending around sex toys. I was like, merry orgasm to you.”

She has made previous headlines for having a sex bench, a stripper pole and a sex swing in her home, plus a room that guests can access through a tunnel with a vagina-shaped door. She also recently made an NFT about her vagina with artist Chemical X.

Last weekend, Delevingne was spotted looking “really drunk” at Bravo star Leah McSweeney’s Halloween bash at The Box — where she was videoed nearly falling off the stage while trying to hug up on performer Azealia Banks.

The footage showed the model-turned-actress being caught by a security guard when she almost tumbled off the stage. She then bounced back and bowed to Banks.

The source hedged that it wasn’t just Delevingne — but that “Everybody was drunk at that debaucherous party.”
