(Cover) - EN Showbiz - Jessie J reportedly feels she's been "picked on" while on the judging panel of The Voice.

The British songstress stars as a mentor on the UK version of the hit TV talent show alongside will.i.am, Sir Tom Jones and The Script's Danny O'Donoghue.

Speculation that there is friction between will.i.am and Jessie has been rife and now a source has revealed that Jessie feels further backed into a corner.

"Will has said he doesn't think Jessie is making an impact, while she's adamant she won't change for anyone. Jessie feels like she's been picked on and forced to be more controversial just for ratings," a source told British magazine Closer.

"She's told friends, 'They want me to be nastier, but I'm not going to ruin my music career for a TV show.'"

Tom and Danny are said to be steering clear of the controversy.

"Danny's furious about the fallout and Tom frankly thinks the rows are embarrassing - he's privately made it clear he'll walk at the end of the series if it carries on like this," the source said.

Jessie recently appeared on The Graham Norton Show where she called parts of the singing competition show "lame". (C) Cover Media
