Lamar's dad Joe Odom appeared to be in good spirits during a quick errand run at Walmart in Las Vegas near the hospital where his son is said to be recovering from an apparent overdose last week.

We spotted Joe shopping for a suit the other day and he seems to be making use of it during his time in the Nevada city. He's still accessorizing with his usual baseball cap.

Odom has been by his son's side since Tuesday, when the former NBA star was admitted to Sunrise Hospital in Las Vegas after being found unconscious in a brothel bedroom. Khloe Kardashian has been by her estranged husband's bedside since that day as well, and has even spent a few nights in Lamar's room.

Lamar's former teammates have been sending well wishes as well -- in fact, former player Joe Smith, who played with Odom on the Lakers in 2010-11 recorded a song in honor of his pal called, "If I Die Tonight." Sounds kinda depressing to us, but maybe some of Lamar's friends are finding comfort in this tribute. Take a listen ...
