The moment spread throughout social media, with many labelling the celebrity couple's daughter as a "mean girl".
However, Loppin de Montmort came to her fellow debutante's defense.
"[Apple's] genuinely the nicest girl ever! She really doesn't deserve an ounce of what she's getting," Loppin de Montmort told People.
"She was the nicest girl ever towards not only me but all the debs!"
Martin herself also addressed the rumours in a now-deleted TikTok posted to her friend Ava Crox's account, per Page Six.
Martin and her friends seemingly addressed the controversy as they lip-synced to an audio clip that said "I don't know how anyone has a problem with us. We are such a delight.
"We are two of the funniest girls and I know us, like offline," it continued.
