Danny Jones says his sister Vicky will "smash it" when she appears on 'The Voice' tonight (25.01.14).
The McFly singer has thrown his support behind his sibling and is confident she'll make him proud when she tries to convince judges will.i.am, Sir Tom Jones, Kylie Minogue and Ricky Wilson she can be a star.
He told the BBC: "[I wish her] all the luck in the world ... I know she will smash it."
The rocker insisted Vicky has a "great voice" and tips her to do well when she takes to the stage in front of the nation on tonight's episode.
He said: "Obviously I support my sister in anything she does. Vicky is a great artist, with a great voice and a great personality."
Meanwhile, his hopeful sibling has dismissed the idea her famous brother means she shouldn't get a chance on the show - and claimed she needs "this opportunity".
She added: "People might think I don't deserve a place on this show because of who my brother is.
"What I'd really like people to know is that I need this opportunity as much as anybody else does. Believe me - I've been trying for ten years."
