BACHELOR contestant Kat Hurd has a secret party past – and an arrest record – that could be a huge turn-off for teetotaler Juan Pablo Galavis, say insiders.

According to court documents obtained by The ENQUIRER, Kat was busted in 2004 for possession of alcohol under the legal age. Not only that, her Instagram page included several photos showing alcoholic beverages. And that’s sure to be a big no-no for Juan Pablo, who’s looking for love on Season 18 of the hugely popular TV dating game!

Just recently, the ex-pro soccer star tweeted that he doesn’t drink alcohol at all, and now the ABC show’s 8 million-plus viewers must be wondering if Kat’s wild ways will be her downfall. “Kat knows how to have a good time,” an insider revealed. “And from the looks of her social media accounts, she’s still very much a party girl.”

But Kat was in tip-top form when she debuted on the show, and she made a great first impression with a plea for salsa lessons from dance enthusiast Juan Pablo.

The 29-year-old beauty should be able to teach him some fancy moves of her own. She boasts a master’s degree in exercise science and recently joined the NBA Phoenix Suns dance team.

Although Kat – who also works part time selling medical devices – and Juan Pablo have a lot in common, the booze could be a deal-breaker considering Juan Pablo’s disdain for the bottle. But Juan Pablo is not exactly squeaky-clean. As The ENQUIRER reported, records show the 32-year-old hunk was a deadbeat dad who was forced by a court to pay back child support for his young daughter Camila with his ex-girlfriend, actress Carla Rodriguez.

Said the source: “Despite their pasts, Kat and Juan Pablo may be meant for each other.”
