Khloé BETRAYED! Sexy College Student Claims Kardashian’s Boyfriend French Montana Tried To Hook Up With Her In His Tour Bus: He Said ‘I Have A Lot To Lose . . . You Know That I Have A Girlfriend!’

Her family warned her to stay away from her bad boyrapper boo — and now maybe Khloé Kardashian will finally listen.

In a shocking Boston radio interview, Fisher College student and “Matty in the Morning” show intern Mariela revealed Kardashian’s boyfriend French Montana, 29, attempted to hook up with her after a June 20 club performance in Lawrence, Massachusetts.

The budding journalist, 23, said she initially sought out a solo Montana after the concert to score an interview for her YouTube channel. (Kardashian was in Los Angeles celebrating niece North West’s first birthday.)

“I love the entertainment industry,” the Dominican Republic-born beauty explained today on KISS 108. “He’s the number 1 New York rapper!”

When she snagged Montana’s manager to make the request, the hip-hop star — who has been inseparable from Kardashian, 29, since April — allegedly looked Mariela over and said, “I’ll give her the interview. But first, I have to interview her.”

“French kicks out all the other girls and takes my cell phone away. Before he takes my phone, he says, ‘Here, call me so I can have your number in case you get lost.’ I have his number, that’s my proof,” Mariela claimed. “We’re making small talk, then he says, ‘Let’s go to my tour bus so we can do the interview.’”

Once they climbed into the bus, Montana began sweet-talking the young Lawrence resident.

“He says . . . 'Whenever you want to visit me in New York, I’ll fly you out there,'"Mariela continued.

Suddenly, Mariela says Montana’s entourage left the bus— leaving the two completely alone.

“He climbs on top of me,” she said. “I say, ‘I’m not about this life. I have morals. I have a lot to lose.’ He says, ‘I have a lot to lose, too. You know that I have a girlfriend!’”
