Isabella Sophie Tweddle (born 27 May 1999), better known under the stage name Billie Marten, is a British singer-songwriter and musician from Ripon in North Yorkshire. Her stage name came from her family's desire to keep her real name private because her music career started when she was a tween.[1] She first came to prominence at the age of twelve when a video on YouTube of her singing garnered thousands of views.[citation needed] She released her first EP at the age of fifteen in 2014, and her second EP a year later. At the end of 2015, she was nominated for BBC's Sound of 2016 award.
