Whitney Houston sure knows how to pick ‘em!

A woman on her boyfriend Ray J‘s new reality TV show claims the rapper got her pregnant during filming of his VH1 show For The Love Of Ray J, The ENQUIRER has learned exclusively.

As The ENQUIRER previously reported, the troubled pop star was furious when Ray J, 28,  began taping a trashy reality show with the premise of finding the "perfect" woman for him.

Now Whitney’s worst nightmare has apparently come true.

Monica Leon, 22 – aka Danger – says she is carrying Ray J’s baby. She had sex with him during production, Monica says, and is now more than three months pregnant.

"There is no way the baby can be anyone’s but Ray J’s," Monica told The ENQUIRER in an exclusive interview.

The young mom-to-be told The ENQUIRER the unexpected pregnancy was an indirect result of the reality show’s too-close-for-comfort premise.

"I was locked in a mansion with him and 13 girls from October until the end of December," she said. "Toward the end of the first week of filming, we made love for the first time – and we slept together every night after that!

"I didn’t want to fall for Ray J, but he was so charming it became impossible not to. I was in love with him, and as strange as it might sound, I think he loved me."

In a shocking disclosure that will torture the 45-year-old Whitney, Monica says Ray J, the singer’s on-again, off-again boyfriend, always insisted he was "single" during production of the show.

"He said he wasn’t in a relationship and was genuinely looking for the one. He didn’t mention Whitney once the whole time he was with me."
