The Voice-USA promo photo

Shakira and Usher are replacing the departing Christina Aguilera and Cee Lo Green.
The judges may have changed but the game is still the same as The Voice gets ready for its season four premiere next month.
As the newly released promotion picture reveals, the new mix promises to be just as exciting as the former.
Series regulars Blake Shelton, Adam Levine and host Carson Daly pose with newcomers Usher and Shakira.
The foursome stand grouped together dressed similarly in black, with Usher's red boots an eye-catching touch.
Shakira stands to the side with hand on hip, looking svelte in a shimmery gold top and skin-tight black trousers finished off with high-heeled platform boots.
While some may be sad to see Christina go, the Colombian singer-songwriter is sure to add some fresh appeal to the NBC talent competition series.

'I would say the competitiveness is up,' Usher recently remarked about his gorgeous new sidekick. 'We've replaced Cee Lo with somebody that's just that much more aggressive. And Christina was always competitive, [but] now you've got four that are just killers up here.'
And Adam agrees. 'You have a pregnant, hormonal Colombian,' he said. 'She's ready to bust some heads. She ain't messing around.'
Shakira, 35, was pregnant during some of the auditions that started in January, but she and partner Gerard Pique welcomed their bouncing baby boy on January 22.
