Khloe Kardashian is said to have been warned by her family to dump French Montana after becoming convinced he used her sister Kim Kardashian West as a cover to be unfaithful to her.

The 'Keeping Up with the Kardashians' star's famous family are said to have had a heart-to-heart talk with her earlier this week after becoming suspicious of her on-off beau.

The Kardashians - including Khloe's sister Kim Kardashian West and mum Kris Jenner - believe French has been unfaithful to Khloe and think he even used Kim as a cover for his infidelity, gossip site TMZ.com reports.

During a recent trip to Dubai, French is believed to have been hooking up with an attractive woman in between bumping into Kim long enough to have his picture taken with her in order to trick Khloe into thinking he was simply hanging out with her sister and other pals.

However, the 'Ain't Worried About Nothin' rapper's plan is said to have unravelled when Kim arrived back in the US and told Khloe she'd spent very little time with French, leading to the family becoming convinced he used Kim to deceive her own sister.

Meanwhile, French recently claimed he would refuse to sign a prenuptial agreement if he were to marry Khloe after it took him two years and $2 million to finalise his divorce from ex-wife Nadeen Kharpouch.

He said: "I just settled a divorce and gave somebody money."

The 30-year-old star added that there would be "no prenups" if he and Khloe decide to tie the knot.
