Sloane also told JustJared.com, “It looks like she was happy to have it happen, but it was not consensual.”

Perhaps unsurprisingly, it has been revealed that Elkann had cast the winning bid on a very special Victoria’s Secret Fashion Show Experience, setting him back a cool $196,000.

When contacted by New York Daily News, a rep for Elkann declined to comment on the saga. Despite stealing headlines for all the wrong reasons, Elkann did perform one good did throughout the night, donating a customized, green camouflage-painted Ferrari 458 that sold for $1 million.

“I am honored and proud that my all-time favorite and cherished Ferrari 458 will benefit @amfar and support the battle to defeat Aids,” he wrote on Instagram , adding ,”It was an honor to be on tonight’s stage. United to fight Aids together. #amfARCannes #fightAIDS #amfAR.”
