It's nice to hear someone give the celebrities some very practical advice on improving their faults, and the advice seems very sound, but her delivery and vocal style drive me mad.
As well as the constantly repeated "yar" (already mentioned) and "OK?" , the rise at the end of EVERY sentence is so irritating! I've heard her speak in an informal setting and she isn't half as "mannered" - in fact, I don't remember her speaking like that when she guested last series.
Unfortunately, I find her delivery rather boring, but if she would only speak a bit faster and drop the irritating bits, I think she could fit into the show very well. She certainly seems determined to give the celeb. dancers a lot of encouragement.
