Recovering Lamar Odom is Grateful to Khloe Kardashian

Former NBA star Lamar Odom is making progress in his recovery and is reportedly grateful to his estranged wife Khloe Kardashian for looking after him.

Khloe has been caring for her estranged husband ever since he collapsed at a brothel in Nevada in October and Lamar, 36, recently moved into a rented home in the same gated community as Khloe, reported People magazine.

"He can move around alone, and he can communicate much better. In the beginning, he couldn't talk at all. He knows how much Khloe has been there for him, and he is so grateful," a source said.

"The therapy can be incredibly frustrating and he has hard moments, but Lamar is a former athlete. He's strong. And he really wants to get better. Khloe visits him at his house and Lamar hangs out at hers."
