Nicole & Antonia Have a Secret Language
GettyNicole and Antonia not only share a special bond, but they also have a secret language.
While talking with WSJ Magazine Editor in Chief Kristina O’Neill (via the Daily Mail), Nicole recalled a dinner she once enjoyed with her sister and actor Hugh Grant.
“My sister and I were speaking our secret language and Hugh was fascinated, because my sister and I have this language that we can speak so we can be understood in a crowd and nobody can understand us,” Nicole explained.
When asked by O’Neill to reveal more about the language, Nicole admitted, “If I end up telling you then you’ll be able to decode it.”
Saying that the secret language is “silly,” she also explained that it’s been useful.
“It is helpful, let me tell you. It was really helpful when we were like at parties and they were and we had our boyfriends and stuff we would be able to use our language and they’d all be like ‘What?'”
She added, “It’s a really good tip all the sisters out there.”
