Jessica Simpson might swear by her snake semen drink that she says helps her sing … however at the very least one skilled tells TMZ the reality is much more of a sticky state of affairs.

This is the deal … Jessica not too long ago raved to us about her secret specialty Chinese language herb cocktail that she says has legit serpent swimmers in it — all on the advice of her vocal coach.

Zoologist and “Reptile Royalty” star Jay Brewer tells TMZ … it is extremely unlikely Jessica’s concoction has any precise snake sperm in it … ‘trigger frankly, it is not that straightforward to return by (no pun)!

It appears extracting the fluid is tremendous robust … and even within the largest snakes across the globe, the quantity is normally minuscule.

To be clear, Jay ain’t calling Jessica a liar … he simply suspects she’s been duped — and the key ingredient she’s truly consuming is snake oil, AKA nothing particular.

That stated, Jay stated something is feasible … and if JS is basically ingesting snake semen, the potential advantages would most likely be a results of stem cells.

After all, she is not the primary celeb to show to animal sperm for private acquire … Kim Kardashian and Jennifer Aniston each swear by salmon sperm as a path to reaching younger-looking pores and skin.

The entire state of affairs reminds Jay of a practice carried out in Southeast Asia the place locals put the gall bladder of a snake of their booze and drink it — to carry them luck.

Whether or not it’s a gall bladder for luck or semen for the vocals … Jay tells us it’s all BS in his e-book … and only a mistreatment of animals.
