Would-be singing star Damian Dalton Smith embarrassed his little sister, actress Sheridan Smith, when he appeared on The Voice and told coach Ricky Wilson she fancied him.
Viewers will see Damian try to win a place in the show's blind auditions tomorrow while Wilson, Sir Tom Jones, Rita Ora and Will.i.am sit with their backs to the contestants who try to convince them to turn around and send them through to the next round.
Damian, 39, said: " I'm very proud to say that my sister is Sheridan Smith. Before Ricky Wilson even opened his mouth I said, 'Ricky, my sister fancies you, by the way'. He went bright red and said, 'Erm, is she here? Over to Will.i.am...'."
He added: "She's a very proud sister, she's over the moon. But when I told her what I'd told Ricky, she screamed down the phone, 'Oh my god! How embarrassing!'."
He is not the only singer in the family - his sister famously recorded some of Cilla Black's biggest hits when she played the Liverpudlian star in a TV biopic and she has joined his band, The Torn, on stage.
He s aid: "Whenever I'm with the band and Sheridan has time off she'll get up on stage and sing with me. She does Dolly Parton's Nine To Five because mum and dad are a country and western duo, The Daltons. We're all in it together.
"We did a festival last year where mum and dad played, my band headlined, Blue and Peter Andre were there, Sheridan got up as well - it was a family affair.
"Growing up we'd go up and down the country with mum and dad and sit backstage with a cup of Coca-Cola and a packet of crisps. All through our childhood we'd be entertaining the rest of the family."
Damian said he had no problems with being known as Sheridan's brother: "I will always get, 'Damian, Sheridan Smith's brother', because she's the one who's made it first. But I'm so proud of her and she's so proud of me that it makes no difference whatsoever. If it is an advantage, then so be it. It's great, why would you knock that?"
:: Damian's audition can be seen on The Voice this Saturday on BBC One at 7.15pm.
