As she prepares to walk down the aisle with her third husband in May, concerned Kim Kardashian advises her younger sister Khloé to stay away from her latest love interest, French Montana.

Newly single Khloé Kardashian and the "Pop That" rapper have frequently been spotted together in past few weeks, and Kanye West's wife-to-be is certainly not rooting for them. "Kim is telling Khloe that she should be really careful with French after everything she just went through with Lamar," a source said. "He's got a lot of family drama that Khloe could get dragged into and Kim doesn't want her to have a difficult romance this time."

As the Keeping Up with the Kardashians reality star went through the publicized split from former NBA player Lamar Odom not too long ago, French Montana also has a complicated relationship history. He remains married to Deen Kharbouch, with whom he has a four-year-old son, Kruz. According to his estranged wife, the "Freaks" rapper has been nothing more than a deadbeat dad who pretty much abandoned his family as soon as he hit stardom.

However, the warnings do not seem to tame Khloé Kardashian at all. In addition to their three consecutive dates in just one week, she was seen jetting out of Los Angeles with French Montana Wednesday evening. The new couple clearly looked very close but was careful not to show any sign of affection, as Kardashian led the way while her beau followed after her.
