Ex 'Party Down South' Star Lil Bit -- Old Bosses Warn ... Your Lotion's Giving Us a Rash

EXCLUSIVE

Taylor "Lil' Bit"  Wright -- who quit the TV show "Party Down South" -- is rubbing her old bosses the wrong way ... with a line of body lotions that capitalizes on her reality show persona.

Wright's been on social media lately promoting a brand of moisturizer and suntan lotion called "Lil' Bit Country" ... but TMZ has learned the network honchos at Viacom (CMT's parent co.) sent her a cease and desist letter demanding she stop using her nickname to promote the skin care products.

The network's position is it owns the name, Lil' Bit -- but sources close to LB tell us she's been using the handle since long before the show ... and she has no plans to yank it off the lotion.
