Lamar Odom back with ex-girlfriend?

London: Lamar Odom`s ex-girlfriend, Liza Morales, is reportedly supporting him in the wake of his split from wife Khloe Kardashian.

The 34-year-old basketball star is said to have rekindled his friendship with Morales just days after the `Keeping Up with the Kardashians` star filed for divorce after four-years of marriage, reported Femalefirst. "Lamar has been talking to Liza in the last few weeks, and she has been a tremendous source of strength for him. Khloe was always insanely jealous of Liza and that is why Lamar distanced himself. He now recognises that was a mistake," a source said. Meanwhile, Khloe is seen with friend Matt Kemp, who previously dated Rihanna. "She and Matt have a lot in common -- same neighbourhood, same friends, and same love of family," the source added. Rumours first surfaced that Khloe and Odom`s relationship was on the rocks after multiple women claimed to have slept with him amid allegations he was addicted to cocaine.
