Ferguson "wasn't looking for Juan Pablo to be the one," a source told Life & Style. "She was just there to make her ex [Detroit Pistons basketball player Rodney Stuckey], who has a new girlfriend, notice. She wanted to make him jealous."
The source explained Ferguson -- who has been portrayed on the show as a sweet, quiet and vulnerable single mother -- has yet to show who she really is.
"Cassandra's one of the craziest girls of the season," said the source. "She is absolutely nuts."
As for Joynt, she reportedly wants very different things out of life than Galavis, a 32-year-old single dad and former pro soccer player from Venezuela who currently resides in Miami, FL.
"She doesn't have real feelings for Juan Pablo," another source told Life & Style. "She lives in Germany and always planned on going back there. She doesn't want to get married and have a child. She's putting her career first right now."
Two other bachelorettes also reportedly have sticky pasts, however, Galavis already chose to eliminate them.
Lauren Solomon, a 26-year-old music composer from Austin, TX, allegedly cheated on her fiance before going on the show. She was reportedly set to wed Blake DuPlant, whom she met on NBC's Minute to Win It game show, but she never walked down the aisle.
"She told the girls in the house that the engagement was called off, and was vague about the details. She later admitted what really happened," an insider told the magazine.
"She cheated, he caught her and that's why it ended!"
Elise Mosca, a 27-year-old first grade teacher from Forty Fort, PA, behaved in a wholesome manner during her time on The Bachelor. For example, she refused to pose naked for a charity photo shoot and was proud of the fact she always tried to set a good example for children.
However, another insider told Life & Style that Mosca worked as a bikini-wearing cocktail waitress at a Los Angeles club called the Playhouse and previously hooked up with former Jersey Shore star Mike "The Situation" Sorrentino.

"[She] acted very demure. She'd say she's a teacher and wouldn't want to do things to compromise her relationship with her kids," said the second insider.
"She wanted The Bachelor to be a stepping stone," a Mosca co-worker added, "because she likes the Hollywood scene. I think the show is going to give her 15 minutes of fame."
