Listen to Lorde on iHeartRadio

The sister of pop newcomer Lorde is making her debut.  Fifteen-year-old India Yelich-O'Connor is getting attention online for a cover she recorded of A Great Big World's "Say Something."  

India, who seems to be sticking with her birth name, is three years younger than her Grammy-nominated sister.  Their voices are already being compared, but it doesn't look like the two have much in common otherwise. .

Here she is hanging out with Cody Simpson! 

India doesn't share her sister's signature curly brown locks or moody expression.  Her Soundcloud profile photo shows her as smiling blonde teen.  And she doesn't seem to have any plans to record professionally just yet. 

India tells "Fairfax Media" that she only uploaded the cover "for a little bit of fun."
