‘Voice’ shake up?

Christina Aguilera and Cee Lo Green could soon be fighting to get their judging jobs back on “The Voice.”

The singers’ giant red chairs are being filled for the upcoming fourth season by Colombian sensation Shakira and R&B star Usher — a move at first believed to be just temporary.

But now NBC says it hasn’t decided who will be invited back for future seasons.

“Once you are a coach, you are a coach,” Paul Telegdy, the network’s head of alternative programming, told The Post yesterday.

“That has been our philosophy with these guys. Do we envision [Usher and Shakira] serving on multiple seasons? Absolutely.”

“[But] Shakira is expecting a baby. I am not going to be making predictions about what the mother of a newborn is going to be doing 6 months from now.”

Aguilera, arguably the show’s biggest star, was reported to be earning $225,000 per hour — triple that of her fellow judges — when the show premiered in April 2011.

The buxom singer has also been involved in a long running, nasty public feud with fellow judge Adam Levine.

“Adam talks a ton of s – – t about Christina and makes fun of her behind her back,” a show insider told Us Weekly last summer.

Like Aguilera, Shakira — who is best known for her dance hit “Hips Don’t Lie” — will be the only woman on the judging panel.
