According to RadarOnline, Odom has been in contact with his ex-girlfriend after Khloe filed for divorce on December 13.
"Lamar has been talking to Liza in the last few weeks, and she has been a tremendous source of strength for him," the source added, "Khloe was always insanely jealous of Liza and that is why Lamar distanced himself. He now recognizes that was a mistake."
According to Hollywoodlife, the NBA star is feeling the stress roll off his shoulders by separating from his wife of four years and her "Keeping up with the Kardashians" family.
A source close to the couple says Lamar knows about MLB star Matt Kemp's relationship with Khloe and doesn't mind it, "Good luck to whoever she's with now," the source added, "It's better a new dude than him. Now he doesn't have to suffer with all the headaches and demands and all of her family pressure."
Now the divorce is expected to be cut-and-dry, Lamar is pleased to finally be out of the reality TV world, "He's relieved he's no longer a part of all that media circus," the source continues. "He feels that anyone who dates her next will have to put every inch of their lives on public display, and he's so glad he doesn't have to do that anymore."
