After French Montana was seen all over the news celebrating his new flame Khloé Kardashian's 30th birthday last weekend, a source close to his estranged wife Deen Kharbouch has opened up about the rapper's allweged indifference to his 4-year-old son Kruz.

The "Ballin Out" rapper recently splurged $100,000 on the "Keeping Up With the Kardashians" star for her big day.

"French has purchased a vehicle for someone who doesn't need it. But he's insisted that he would not pay for his child to go to school," the source told Radar Online in reference to the new $50,000 black Jeep he bought Kardashian. "He has never even bought Kruz as much as a toy ever since his shot to fame. This hurts beyond words what he did, does and continues to publicly do for the sake of fame and Kardashian money."

Deen had been P. Diddy's protégé since 2006 until she and Montana, who is signed to Bad Boys Records, started divorce proceedings in 2012. With that being said, the source revealed that the Moroccan emcee is simply spending money he does not have, even using his wife's money.

"He's [not just] blowing his money [but] his wife's money too! He's not a millionaire," the source said. "That's what he does. He makes other people think he's on top. He's a con man. And if the Kardashians are falling for that, that's his MO."

While flying to places with the reality star, the "I Ain't Worried About Nothin" hitmaker apparently has reportedly not called or visited his son in a while.

"Kruz has not seen or spoken to his father in over six months. Nor has his father inquired about Kruz's well-being in over six months," the insider claimed. "Since the fame, he's been a deadbeat. He also threw a birthday bash for this woman and did not attend his son's pre-school graduation. His son was the only child without a father present."

The tabloid website's source continued to criticize Montana's irresponsibility.

"Reports that were printed that claim French visits his son are complete rubbish," the source claimed. "Despite French living and being in New York City he has never spent a minute with his child. What you have here is complete abandonment."

The source then questioned French Montana's thoughtless "devastating" behavior on social media, saying the rapper "posted a monkey on Instagram versus his son. He calls other people family, but he never once asks about his son"

In addition, the insider accused Kardashian as well as her notorious family of being hypocrites.

"The irony is Khloé was the first to oppose her best friend Mallika's relationship with a married man on her show. She was an advocate for her not doing that and now she is doing the same thing," the source added. "I guess only the Kardashians deserve to have two-parent households. They preach 'family first,' but support a man that abandoned his wife and child completely. They enable him in doing so."
