The Fever Pitch beauty was attending an event during February's New York Fashion Week, where she was confronted with questions about the supposed demise of her romance.
She says, "I had this woman from Us Weekly come up to me, and I've never yelled at someone, but, like, I totally snapped at her.
"I was like, 'How would you f**king feel if, like, this wasn't true and someone was questioning your relationship, you know, publicly? Wouldn't it hurt you? You are a human being--think about it!'
"I'm human. And... it does kind of hurt you, but you know what? Stuff like that isn't true. It'll be fish wrap tomorrow."
Of her romance, Barrymore adds, "We're in love, and that's all that anybody needs to know. They can speculate, and they can say anything they want. I know the truth, and he knows the truth. And if he knows I love him, then that's all I care about."
