She seems to be nice, she works her backside off... I don't see any problem with her.
But I wish she'd occasionally go back and do some of that Fozzy Bear style rapping like she did with Mis-Teeq, that always gave me a chuckle.
I thought she was an OK pop singer, never watched Strictly or BGT so can't comment on her judging, but her speaking voice irritates me. And her last song seemed to be just a long naggy moan about her boyfriend not doing the washing up -
