Bo Bruce has said she thinks The Voice needs the straight talking of Jessie J.
The singer - who found fame on the show in 2012 - said she thought coaches Kylie Minogue, Ricky Wilson, Will.i.am and Sir Tom Jones had gone too easy on the contestants in the recent series of the BBC singing talent show.
Bo, speaking at the Home Coming festival in Regent's Park, said: "I felt like there was something missing this year. Jessie was so mouthy.
"It seems so long ago but what I watched wasn't like I remembered."
The 29-year-old also revealed she had had an awkward run in with Kaiser Chiefs frontman Ricky Wilson after tweeting that he looked hot on the show.
Bo said: "I had a really embarrassing thing with Ricky, because I said he looked hot. And then I bumped into him at the Ivor Novello awards and he was like 'Hi Bo' and I thought 'You know I said you were hot, stop it!'."
Bo was a hit with viewers on The Voice for her soulful singing - and opening up about her battle with drink and drug addiction.
But she revealed she has been playing at gigs around the world with a new dance track.
Bo said: "The dance track is so freeing. I felt like before I was singing my heart out and and now I'm just having so much fun on stage."
She added: "My new album is a link between the two but it's not a dance album."
Bo was among the star guests soaking up live music and sunshine at Regent's Park Open Air Theatre for Home Coming, a brand new festival hosted by London members club, Home House.
Festival-goers raised money for the Elton John Aids Foundation and enjoyed performances by Sophie Ellis-Bextor, Maverick Sabre, The Strypes and Suggs.
