WATCH: Rosie goes solo - and she can sing

You all might remember the adorable british duo Sophia-Grace and Rosie that took the world by storm in 2011 with their cover of Nicki Minaj’s Super Bass.

Since the video went viral and the girls have appeared on The Ellen DeGeneres Show on multiple occasions, published two illustrated story books and even starred in their own movie, Sophia Grace & Rosie's Royal Adventure.

Sophia Grace Brownlee is the voice behind the duo while her uber shy cousin Rosie McClelland mouths the words and dances along with her - but not anymore.

Rosie's official Twitter account - run by her mom - tweeted “Who wants to hear me sing? xxx” yesterday and then posted this video of Rosie singing a snippet of ‘Do You Want To Build A Snowman’ from the Disney movie ‘Frozen’.

Who wants to hear me sing? xxx

WOW … She can sing!

Will she pluck up the courage to borrow the mic from cousin Sophia-Grace? We will just have to wait and see.

Well done Rosie
