French Montana's longtime girlfriend is rumored to be so "devastated" by his relationship with NBA veteran Lamar Odom's estranged wife Khloe Kardashian not even her big sister Kim Kardashian has been able to keep the peace.

The 29-year-old Kardashian and Montana began "hanging out" several weeks ago and now HollywoodLife.com is reporting female rapper Trina is said to be slandering the bad boy rapper as an opportunist who took up with the Keeping Up with the Kardashian's star even though they had been dating for years and lived together in New Jersey.

Lamar, Khloe break up rumors

"He dropped Trina and went right on to Khloe," a source told the website of the 29-year-old Montana. "Trina stood by his side through everything and he just discarded her. They were living together, I mean come on. She has no clue what's going on, she's reading about it just like everyone else is."

AllHipHop.com reports up until now Kim Kardashian and Trina were good friends and Kardashian has even tried to arrange a three-way call between all the women to try and work things out.

Lamar believes Khloe fliring with rappers to get under his skin

After four years of marriage, Kardashian filed for divorce from Odom last December, citing irreconcilable differences. Since splitting from his reality TV wife, Odom appears to be turning his career around, signing a deal just this week to join the New York Knicks and Phil Jackson.
