Attention filthy rich LA Lakers fans — Lamar Odom does not have a cash-strapped assistant … something director Penny Marshall learned after getting jacked for several thousand bucks.Sources tell TMZ the double-cross started at a Lakers game last month … when a man claiming to be LO’s assistant gave Penny a phone number he said was Lamar’s.

We’re told Penny and the person she thought was Lamar texted back and forth for several days — when finally “Lamar” asked her to loan his assistant a chunk o’ cash. Ever the faithful Lakers fan, Penny forked over more than five grand to the faux “assistant.”

Hook. Line. Sinker.
