On July 4, Amber Portwood was arrested for domestic violence after allegedly attacking her then-fiance, Andrew Glennon, with a machete.
Amber has accepted a plea deal in order to avoid jail time, but she still denies that there was any sort of weapon involved in the attack.
Now, however, YouTuber Katie Joy claims to have uncovered evidence that contradicts Portwood's claim.
Indeed, the footage, republished this week by TMZ, does present compelling evidence that Amber used a machete and tried to break down a bedroom door, which is consistent with Andrew's claims.
It's unclear if MTV execs have seen this footage.
As you may know, the network has reached the controversial decision to continue employing Portwood despite the evidence against her.
Will this video threaten her future employment with the network?
Probably not -- but it leaves little doubt as to her guilt.
