Sophia Grace Brownlee and her cousin Rosie McClelland shot into the public eye in October 2011 when Ellen DeGeneres discovered a cover the two tots had made of Nicki Minaj's Super Bass.
Sophia Grace, 19, sent shockwaves across the internet when she announced that she is pregnant with her first child in a YouTube video.
The expecting mother has come a long way from her talk show debut that saw her wearing elaborate tutus as she quickly became a favourite of the celebrity host alongside her cousin Rosie, 16.
