Ummm ... we spotted a "reformed" Lamar Odom out this past weekend looking a little shady ...

The former baller leaves an office building, kinda walks around, slyly checks out a gaggle of girls fan geeking over the overdoser, and eventually has one of the fine ladies jump in his chauffeured car! But hold up, that's his GIRLFRIEND Sabrina Parr. Phew! For a minute there we thought Lamar had fallen off the wagon ...
