The images see new coaches Miley Cyrus and Alicia Keys feature.

The low-quality pictures include the 'Wrecking Ball' star playing an acoustic guitar.

The duo will join returning judges Adam Levine and Blake Shelton on the NBC show.

The eleventh series of The Voice is due to air in the US in September.
