And considering she is the Dreamboy's ex, she's speaking from experience!
Insisting Rogan really is as bad as he is made out to be on TV, the dark-haired beauty told The Daily Star her former flame knows exactly how to get girls to fall for him, despite his womanising reputation.
During the second series of Ex On The Beach, fans of the show were hopeful Jess would be the one to get Rogan to settle down. He described her as the "one that got away" and pulled out all the stops to rekindle things when the pair were reunited.
However, that didn't stop him and his wandering eye, and Rogan soon felt the wrath of Jess when she spotted him dragging another girl off to bed in front of her. Ouch.
Despite testing his relationship with Jess countless times on the show, Rogan soon managed to win her over, confessing his love for her in the series finale. And while we all thought that was him declaring himself a one-woman man, we later found out their relationship only survived a matter of weeks.
Looking back on her time with Rogan, Jess said: "I can see why girls fall under his spell. He is quite cheeky, cute and has a good body - he just knows how to work his best assets... Rogan is the ultimate Casanova."
But despite his charming ways and his buffed up bod, Jess insisted there was no chance of her giving things another go with him.
"I don't care about Rogan anymore," she claimed. "I've moved on from him now, there are no feelings left at all."
Jess' comments come after viewers recently watched Rogan make his Ex On The Beach return.
Back for more, the 25-year-old just couldn't keep away and this time round, he's hoping to find a girl to tame him. That, or make just as much mischief as before!
Shortly after surprising ex Jemma Lucy, Rogan was already causing a stir. Sent on a date with Megan McKenna (Jordan Davies girlfriend), he managed to persuade the Essex beauty to locks lips, potentially ruining her romance with Jordan from doing so.
How did he do it? Body shots. Rogan claims they never fail and low and behold, Megan didn't say no when it came to sucking a lime from his mouth. While she claims that didn't count as a kiss, her beau Jordan wasn't so convinced.
Tension grew between the couple and when Jordan defensively denied that Megan wasn't his girlfriend, she chose to get her own back spending the night with Rogan in the 'Love Room' instead.
