Nicole Prascovia Elikolani Valiente, aka Nicole Scherzinger, has announced via the medium of Instagram that she'll voice a character in the next Disney film.
Please read the caption below this picture for more information on Sina and Moana etc.
Here's some blurb about the film which we've copied and pasted from Wikipedia:
In ancient Oceania in the South Pacific, the young Moana is a born navigator who sets sail in search of a fabled island. During her journey, she teams up with her hero and legendary demi-god Maui.
Nicole's character Sina is Moana's mum, 'FYI'.
