Phaedra Parks' Horror: Jailbird Ex Apollo Nida Breaking Rules Behind Bars

As Phaedra Parks fights to pick up the pieces, her disgraced ex-husband Apollo Nida keeps getting into more and more trouble behind bars, RadarOnline.com has exclusively learned.

The Real Housewives of Atlanta father of two, who began serving an eight-year sentence on bank fraud and identity theft charges in September 2014, has been "pissing off" fellow prisoners at New Jersey's Fort Dix correctional institution with his rude moves and rule breaking, an insider tells RadarOnline.com.

"Apollo doesn't respect the other inmates," the source says. "He has no regard for simple etiquette."

In one instance, the 37-year-old con man refused to wait in line for the microwave, and instead cut in front of the other men during mealtime.

Another day at recreation, he interrupted a pool session in order to start his own game.

"Apollo thinks he's better than everyone else because he's famous," the insider explains. "Obviously, his behavior doesn't win him any friends."

As RadarOnline.com exclusively reported, Nida was forced into the prison's maximum security facility when officials caught him smuggling a secret cell phone, a serious violation.

The former fitness trainer might be smart to make prison pals— he won't be eligible for release until 2020.
