Whitney Houston and Robyn Crawford once plotted to confront Wendy Williams outside the former DJ’s radio studio after Williams discussed private details of their alleged relationship on the air.

“[After] a long day’s work, we’d get in the car, the radio was on … everyone lived by the radio back then. We’re in the car and you’re like … talking like you lived with us, like you’re roommates with us,” Crawford tells radio DJ-turned-TV host Williams on her talk show Tuesday.

“We’d be in the car and Whitney would be like, ‘Who is she? Who is this woman? I don’t even know what she looks like!’ Our plan was to go down to Hudson Street … waiting for you right outside,” Crawford said.

Williams replied, “Robyn, I can’t even fight! I would’ve run.” Crawford assured Williams, “We weren’t going to fight you — we just wanted to see you face-to-face and have a chat.”

Crawford’s new book, “A Song for You: My Life With Whitney Houston,” confirms the long-discussed rumor she had a romantic relationship with Houston.

Williams tells Crawford everything she gossiped about on the radio, “all came true. A lot of what I said is in this book!”
