One of the shots -- taken nearly a year ago -- shows McGee, who claims to be 24, licking a knife while wearing a swastika armband. In another photo, McGee has the letter "W" tattooed on her left leg and the letter "P" on her right.
TMZ claims McGee tells people that the letters stand for "white power."
In court papers filed in San Diego in January, McGee's ex-husband Shane Modica -- with whom she has a 5-year-son, Avery -- claimed that she also had a large swastika tattooed on her stomach and often spelled out "White Power" in magnets on her refrigerator.
He accused her of dating gang members and performing in strip clubs under their son's name.
"As years go by, Avery's mother slips more and more into stripping, pills, alcohol and performances she does online, pornography that she has brought into our home," he wrote in the papers.
"I believe that Michelle is mentally ill and should be in the care of a therapist, which the court ordered her to see, but she refuses to do so," he continued. "She is supposed to take medication for bipolar disorder, but she doesn't."
McGee has not publicly commented on TMZ's report or her ex-husband's claims.
