It was reported last month that Lizzy Pattinson had successfully passed an auditioned for The X Factor.

So it was only natural that Robert would eventually be questioned on his sister’s audition, and it seems that he couldn’t be prouder of his sister: "I'm like, so ridiculously proud of her. I would never have the balls to do that, ever, in a million years. I can't believe she's done it. So, it's amazing."

Awww, how sweet. This isn’t the first time Robert has praised Lizzy’s musical attributes as she also contributed to background vocals for the Twilight and Twilight: Breaking Dawn – Part 1 soundtracks.

Robert is also famous for his music and is rumoured to be recording an album himself. It seems music really does run in the family.
