*A simple trip to the fragrance counter at Neiman Marcus Thursday night landed former “American Idol” finalist Chikezie Eze in a Beverly Hills jail on charges of felony identity theft.

According to TMZ.com, Chikezie says he attempted to purchase two bottles of cologne with his Neiman’s credit card — a card he had never used before. Chikezie says the clerk flagged the plastic, called security and he was taken downstairs for questioning.

The singer says he was told … something was “untrue” on his credit card application, though he had no idea what it could be.

Chikezie says, “They said they were waiting for someone to use the card and when they did they would pull them down.”

He was detained by store security until police arrived and booked him on felony identity theft. He was taken to jail in Beverly Hills and held on $50,000 bail.

Chikezie tells TMZ he has no idea what information on the application might be false, adding, “I am who I am. It’s not like I can hide that.”

He said security mentioned something about the name of his company — Advanced Business Strategic Solutions — on the application, but didn’t know if that’s why Neiman’s flagged the card.

Chikezie says, “I haven’t done anything wrong myself and I’m pretty confident nothing is going to happen.”
