Greg Hardy is breaking his silence on his recent domestic violence arrest … insisting he and his family “are all perfectly fine” — despite the disturbing allegations that were made against him last week.

Hardy took to his Instagram page to share the update with his followers on Tuesday … just less than a week after he was thrown behind bars for allegedly getting physical with his girlfriend during a dispute at their home in Richardson, Texas.

Hardy shared two videos and a picture of him getting cozy with his family … with a caption that read, “Please stop spreading what these chaos machines post, they don’t know any facts then fuel the fire that effects my kids and my wife.”

According to the Richardson Police Department, Hardy put his hands on his GF after she had accused him of cheating on her. Cops wrote in documents Hardy’s girlfriend told officers the former Dallas Cowboys pass rusher pushed her and also put one of his hands around her neck.

The docs stated cops noted scratches and redness on the accuser’s body that were “consistent with a physical altercation.”

Hardy did tell cops, according to the docs, he was involved in a dispute with his GF, but he was “adamant” he never did anything more than merely move her out of the way.
