Lamar Odom back with ex-girlfriend Liza Morales?

American basketball player Lamar Odom has reportedly rekindled his romance with ex-girlfriend, Liza Morales, after his split from socialite Khloe Kardashian.

The 34-year-old is said to be back with Morales, with whom he has two children, Destiny, 15, and Lamar Jr., 11, just days after Khloe filed for divorce here.

"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 told gossip website tmz.com.

Meanwhile, Khloe is reportedly "taking it really slow" with her new beau, Matt Kemp.

A source said that the rumoured couple has a lot in common, adding, "same neighbourhood, same friends, and same love of family."
