The husband of UFC star Andrea Lee has come under fire after a photo of him emerged on social media exposing his swastika tattoo.

Lee posted a snap of the pair together at a lake, and the Twittersphere quickly noticed the pro-Nazi ink on Donny Aaron’s left arm.

On Saturday, Aaron also addressed the controversy, calling his tattoo a “20-year-old mistake” in a tweet. He also said his ink doesn’t define him and if it was possible, he would get it removed.

There were also suggestions Aaron had a double lighting bolt — the symbol of the SS, the Nazi military force — tattooed on his right arm.

Unsurprisingly, Aaron and Lee got heat on social media.

Lee is the No. 12-ranked flyweight contender and has a 9-2 record. She is a former flyweight champion in MMA promotion LFA.

Her last fight was a unanimous points decision win over Veronica Macedo at a UFC Fight Night on May 19.
