Khloe Kardashian and Lamar Odom's marriage seems to finally be over. According to a report from Hollywood Life, the "Keeping Up with the Kardashians" star's estranged husband is allegedly moving on already from their failed union.

"Khloe and Lamar weren't moving forward so he decided to try and make himself happy," a source said.

The report also shared how Khloe Kardashian might have been replaced by Lamar Odom's former girlfriend, Lara Manoukian.

"Lamar has finally moved on and is back dating his ex Lara [Manoukian]. Lamar and Lara were together just before he fell in love and married Khloe," the source revealed.

"He realized they had a good thing and it's even better now after all he's been though. Lara has really been a terrific influence on his life."

"He's really making good progress getting his feet back underneath him," the source added.

Khloe Kardashian is allegedly heartbroken with Lamar Odom's decision to move on from their failed marriage, especially with him reconciling with Lara Manoukian.

"Hearing that Lamar is back with his ex is crushing for Khloe," an insider shared.

"She's heartbroken over it and still doesn't know if she believes it. To find out another woman is making him happy is like a knife to the heart."

"Hearing that he's also doing better than ever living a good clean life while with this woman is even harder to deal with," the insider added.

Even though Khloe Kardashian is said to be hurt that Lamar Odom seems to have given up on their marriage, the 30-year-old reality star has long been reported to be dating French Montana.

According to a report from E!Online, the youngest Kardashian sister and "Don't Panic" rapper were recently seen flaunting major PDA at Miami's Red Bull Guest House. The on-again-off-again couple were accompanied by urban music superstar P. Diddy and R&B songstress Cassie.

"They were acting very much as a couple, French is all about Khloe and can't keep his eyes off of her," a source said.
