After a fan asked Mack if War Machine beat her, she responded with "I didn't let him. But I did stay after several slapping, choking unconscious, smothering, kicking, and throwings."
Mack has since deleted the tweet, so it's unclear at present time what fight fans can take away from the original message.
Obviously it is disturbing if War Machine did commit domestic violence, but maybe Mack deleting the tweet means she was just trolling to get a reaction.
If Mack was just trolling and realized she took things too far, its poor form on her part.
At the time of this publishing, the full story has not been revealed.
Mack hasn't done a follow-up tweet to address the issue, and War Machine hasn't provided much information from his own Twitter handle.
War Machine seems to be more upset by the media coverage he received over the breakup with Mack.
Machine expanded on his thoughts later in the day.
"Ain't nobody made a dime off being interviewed by one of you motherf*ckers! You NEED us, we don't need YOU! F*ck all MMA 'news' sites," Machine tweeted.
War Machine is an MMA fighter who most recently competed under the Bellator MMA banner, while Mack is a world-renowned adult actress.
Hopefully they'll be able to work out their differences and move forward in a positive manner.
