Lil Kim is in danger of losing a huge portion of her fanbase ... after stiffing a large group of gay fans who paid big money to meet her over the weekend.
All the rapper had to do to score a fat $23,000 payday Saturday was mingle with 100 high-paying fans, then do a quick show to help celebrate the club's 5th anniversary.
Not a bad gig, right?
But The Manor claims she showed up late and skipped out on the scheduled meet and greet ... and now they're on the hook for refunds they had to shell out to the VIP fans.
