Khloe Kardashian and French Montana have split for a second time. The reality star is said to have called time on her on/off romance with the rapper, who she split from in September after eight months of dating before reuniting in November, because she felt their relationship was getting "too serious" and it was too soon after her failed marriage with Lamar Odom. A source told Us Weekly: "Khloe just wasn't ready after Lamar [Odom] and it was getting too serious. "She respects and cares for him but just wasn't ready." The pair's latest split comes after Khloe and 30-year-old musician's September separation occurred for very similar reasons. A source said at the time: "They are on a break. The relationship got too heavy and Khloe needed to take a step back." Another insider added: "It grated on her that he became so dependent on her."
