Larissa Dos Santos Lima, 32, appeared on the sixth season of 90 Day Fiance, a reality show about international engagements.
She was booked Friday into the Clark County Detention Center on one misdemeanor count of domestic battery.
Larissa posted shocking photos on her public Instagram account in the wee hours of Friday morning — pointing to a nasty altercation with her husband, Colt Johnson.
She admitted that she scratched back in self-defense before Colt called the police.
Dos Santos Lima was arrested twice in 2018 for domestic-violence-related charges, but both cases were dismissed.
A preliminary hearing was scheduled Saturday morning. Her bail was set at $3,000.
