Lamar Odom — Eating Armenian, But Still RAIL THIN

Lamar Odom ate out last night — Armenian, of course — but emerged from the restaurant looking scarily thin … especially for a guy trying to make an NBA comeback after a months-long drug binge.

Lamar and some friends hit up Gavar Cuisine in Glendale, CA — and he walked out sporting his customary Nike warmup, white tee, and interestingly … a rosary.

LO thinks he can kick his drug habit without rehab AND return to game-shape for the upcoming NBA season, so … if anyone could use religion it”s him.

But judging by his gaunt frame … what he really needs is a couple of double-cheeseburgers.
