Glen “Big Baby” Davis is being sued by a woman who claims the former NBA star screwed up her deal with him Chris Brown, TMZ Sports has learned.

According to court documents we have obtained, the lawsuit was filed Friday in Los Angeles by a pharmaceutical scientist, Dr. Lyndsey Whitewho says after initially embarking on a barbecue sauce project with Davis – and things quickly went wrong.

In her lawsuit, White claims she and Davis agreed to create “Big Baby Q” BBQ sauce in April 2021 … and a short time later she says she gave Davis a $30,000 loan to do the same to get into a weed business together.

A few months later, White alleges in her lawsuit that Davis helped her meet Brown, who then asked White to create a fragrance line for him.

But when Davis was arrested in October 2021 for defrauding the NBA’s Players’ Health and Benefit Welfare Plan – White says everything has changed.

White wrote in her lawsuit that Davis became aggressive — “causing her to fear for her life” — and severed her ties with Brown … resulting in the loss of what she described as “a major client.”

Additionally, White says Davis never paid her back the $30,000 for the marijuana venture they undertook together – and claims the former Boston Celtics forward used the money for legal fees. She also stated that Davis sold the BBQ sauce she created for him and that he never gave her a dime for her role in that business.

She’s now suing for breach of contract, intentional misrepresentation and more… and is seeking unspecified damages.
