Shocking to me, I never even realised she had any other family members since none of them are famous or anything.
Laura Imbruglia is a musician and she has even recorded songs. Her debut album was out on the 14th of October. I suppose she's an indie artiste, but I have no idea. Anyone knew about her beforehand?

I realised she did not even mention her sister in the site. Or that Natalie also did not mention Laura in her site. Even wiki doesn't mention Laura. It's like she never existed.
Laura's music is ok... Just weird, it's so un-Natalie. Her voice sounds deeper and more unsophisticated, her song titles too. She looks a bit like Natalie though, so I guess it confirms that they are indeed sisters.
