Los Angeles - Khloé Kardashian has revealed Kim Kardashian is using "fertility monitors".
The 30-year-old reality TV star admits her older sister, who has daughter North, 16 months, with husband Kanye West, is desperate to get pregnant again as soon as possible.
Asked if she thinks Kim, 34, will be expecting her second child by early next year, the Kourtney & Khloé Take The Hamptons star told E! News: "I don't know. I know she wants one and she's trying for one. They're not doing anything to stop it. You know, on those fertility monitors and everything, figuring it out."
Meanwhile, the reality TV star, who filed for divorce from Lamar Odom last December after four years of marriage, avoided confirming whether she has rekindled her relationship with French Montana.
She said: "We all miss French. We love French."
Asked if they're definitely no longer together, she said: "Well you know, yeah..."
The Don't Panic hitmaker attended her half-sister Kendall Jenner's 19th birthday party in Los Angeles this past Monday, just days after he confessed he still has feeling for Khloé and said she will be his "baby forever".
