NeNe Leakes -- Wedding Planner Is Full Of S**t

NeNe Leakes says the "celebrity wedding planner" suing her for MILLIONS in alleged unpaid wedding bills is straight up lying in a desperate attempt to grab 15 min of fame ... and she owes her squat.

TMZ broke the story ... Tiffany Cook filed a lawsuit in GA, claiming she planned NeNe's June wedding (which will be featured on Bravo) -- but claims the "Real Housewives" star never foot the massive bill. Tiff's asking for more than $2.5 MILLION!!!!!

We caught up to NeNe Saturday night in Beverly Hills to ask her about the nuptial-gate and she GOES OFF saying she NEVER hired the fame-hungry planner. She adds, "I don't owe her a f***ing dime."
