Ever since their breakup, French Montana has reportedly been trying to win Khloé Kardashian back. Is Lamar Odom worried about the pair's possible reunion?

A source previously revealed to Hollywood Life that the Moroccan emcee is "still trying to get her back though, he's still sending her flowers and calling her. ... She's having fun seeing him chase her -- it's great for her ego, but she's over it."

Amid Montana's alleged desperate attempts, Odom was said to strongly believe that nothing can come between him and his estranged wife.

"Lamar was never worried or threatened by French Montana," another source said. "He's whack and so is his music. Who even listens to French Montana anyway, son?"

The former NBA player apparently doesn't think the "Don't Panic" rapper is a "real man," considering his constant baby mama drama with estranged wife Dean Kharbouch, as well as the recent cheating rumors surrounding him and Kardashian's best friend Malika Haqq.

"Lamar figures if French really wanted to be with Khloé and take her seriously, he would have been a real man and would have stepped to her correctly from the jump," the source said. "He wouldn't have been still married, and he for sure woulnd't have had some side piece girlfriend."

Lamar Odom only saw French Montana as nothing but a rebound to Khloé Kardashian from the beginning of the couple's highly publicized relationship.

"Lamar knew from the beginning that French and Khloé's relationship wouldn't amount to anything. It didn't have the right foundation from the beginning," the source said. "Not only that, Khloé was still married to him too. So what's that I tell you? That was all a rebound for Khloé and now Lamar's got the ball and is ready to score."
