Lil Baby Calls Prostitute Claiming He Paid Her $2K a Liar

Lil Baby is telling a proud prostitute queen that she sits on a throne of lies -- after she's publicly calling him a cheapskate for allegedly only paying for her poom-poom with $2,000!!!

A woman who calls herself "Jaw Morant" -- an homage to the famous basketball player while playing up to her alleged explosive mouth skills -- conducted a full-blown interview where she claimed Baby was pinching his pennies.

Similar to DaBaby the other day, the "We Paid" rapper wasn't about to let any smut travel alongside his name online and called Miss Jaw Morant a bald-faced liar, adamant they never met.

No proof of Baby and Le Jaw being seen together, but she claims they did have a run-in that didn't go over so well.
