Khloé Kardashian is "having so much fun" with French Montana.

The 'Keeping Up with the Kardashians' star, who filed for divorce from Lamar Odom after four years of marriage in December, began "casually dating" the Moroccan-born rapper, 29, last month but is taking their relationship slowly.

A source told PEOPLE.com: "Khloé is totally with him. She's having so much fun with him. She wasn't sure at first where things would lead but he treats her amazingly. That makes her feel really good. She deserves that."

The couple have been spotted on numerous dates in Los Angeles recently and took a trip to Arizona for a night out with friends.

The 29-year-old beauty was also spotted walking through LAX airport with the 'Pop That' hitmaker, who is the CEO of Cocaine City Records, for another getaway with friends earlier this week.

But the insider insisted that Khloé isn't rushing into things, adding: "She's not taking it too seriously, just having fun."

The reality TV star split from Lamar, who signed a new multi-year deal with the New York Knicks this week, following months of rumours he was addicted to cocaine and cheated on her.

Her estranged husband, 34, is "unimpressed" that she has moved on already.

A source told Us Weekly magazine: "He thinks Khloé is just doing this to get to him. He's furious."
