TMZ – Tamar Braxton says the triggers that led her estranged husband Vincent Herbert to a jail cell on Christmas day were alcohol and a case of jealousy.

Tamar tells TMZ, “While celebrating the Christmas holiday as a family, after a few drinks and some jealousy, things got a bit out of hand, which is common for most families during the holidays.”

Tamar makes it clear … “There was no physical interaction between Vince and i on Christmas. While I do not appreciate his lack of respect for our family and him allegedly impregnating another woman, I cannot paint him as a vicious abuser.”

TMZ broke the story … Herbert was arrested for spousal assault and taken to jail, where he bailed out after posting $20k.
Tamar went ham a few hours ago on the woman claiming Herbert got her pregnant … calling her a “whore.”

TMZ broke the story … Tamar filed for divorce in October.
