CURVY Christina Aguilera went on live TV wearing a top so low-cut show bosses feared her boobs would pop out!

The star is one of the judges on US show The Voice – an X Factor style show which aims to coach young unknowns to stardom.

But all eyes were on Christina wearing a dangerously low cut, tight-fitting, green top.

A show insider said: “We know Christina is a sexy girl and not shy of showing a bit of cleavage but seriously this was ridiculous. We were fully expecting a Janet Jackson style wardrobe malfunction.”

Christina Aguilera, Cee Lo Green, Adam Levine and  Blake Shelton are the show judges.

Christina Aguilera was herself discovered on a TV show called Star Search and went on to sell nearly 50 million albums worldwide.

The BBC ha just secured right to the UK version of The Voice at a cost of £25 million.

The show was devised by Big Brother creator John de Mol.
