says he is ''ridiculously proud'' of his sister for trying out for The X Factor
. The Rover
actor - whose older sibling, Lizzy Pattinson, recently made it through to the live auditions for the UK series after wowing this year's judges, Simon Cowell, Cheryl Fernandez-Versini, Mel B and Louis Walsh - thinks she is very brave for deciding to appear on the show, and admits he wouldn't have the guts to do it.
The 28-year-old star, who also sings, told Grazia Daily
: ''I'm like, so ridiculously proud of her.'' He added: ''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.'' The 31-year-old singer has provided
backup vocals on songs for various Twilight
soundtracks and even had a top 20 hit in the UK in 2003 with the song "Let the Sunshine In."
