Singer-songwriter Jessie J, a judge on British reality TV singing show The Voice has reportedly banned the three finalists of the show from using micro-blogging site Twitter because she wants them to concentrate on the show.

The pop star feels the finalists – Sarah Cassidy, 31, Matt Henry, 34, and Ash Morgan, 27 – have become too distracted by the fame that comes with being on the reality TV show.

The 25-year-old has even unfollowed them on the social networking site because she is annoyed with their tweets.

“I have said to the team don’t be obsessed with Twitter, I’ve even unfollowed some of them because it gets too much – it’s constant,” dailystar.co.uk quoted Jessie as saying.

“I want to say to them not to get too obsessed with it because it’s 10 per cent of the world, it’s not real. You have to focus on what’s in front of you and not get distracted,” she said.
