X Factor judge Gary Barlow has admitted to not being as enthusiastic about Frankie Cocozza's presence at the live shows as he once was.

Cocozza landed in the bottom two on last week's show but was saved by Barlow, Kelly Rowland and Louis Walsh - who had earlier claimed the singer had lost his swagger.

"On Monday morning I was thinking I'd made the wrong choice picking him," Barlow confessed to The Sun. "I'm doing well with Craig and Marcus but it's Frankie, I just can't ever track him down."

The Take That star also criticised the X Factor contestants for being obsessed with fame rather than focusing on the competition.

"The trouble with the artists this year is they are all obsessed with Twitter and headlines," he said. "It feels like they are all getting a bit above themselves. We are constantly reminding them that they are in a competition. I had a word with all my contestants and I know Kelly Rowland had a word with hers. It's reality check time.

"We are all lucky to be here, we are lucky to be on stage and have millions of people watch us. You don't deserve this. We are lucky. I've found it draining. It reminds me of when I was on as an artist. It is chaos, you've got your nerves, the red light comes on and you're on. It's a lot of pressure. I feel really sick before I go on."

Barlow also confirmed reports that Simon Cowell has told the judges to up their game, saying they plan to improve the show by 10% each week.

He added that Walsh is "in Dublin all week" and "doesn't really care" about his acts. "I'm here to find a star and it's not Johnny," he said
