The tease shows Chyna demanding a paternity test and there’s a shot of her with a needle in her arm … it makes it seem like she herself is saying she was sleeping with multiple guys.
However, production sources tell us the needle is for a routine blood test … NOT a paternity test. We’re also told she has made it clear … Rob’s the only guy who could possibly be the dad.
In fact, we’re told Chyna and Rob planned the pregnancy almost from the get-go. They tried for several weeks to do the deed before she actually got pregnant, despite the fact they only dated each other for a minute.
Chyna actually did tell Rob at one point he might not be the father, but did it “to get under his skin because she was pissed off at him.”
