The PR department must be gutted... they used to have quite a cosy relationship with the Daily Mail, didn't they? When they last did the Beauty Bash they had Daily Mail involvement, certainly the year I went.
I don't think it's a particularly well written piece - my thoughts as I read it was that it was lazy journalism and cheap shots. They can't be bothered to make any sort of distinction between QVC US and UK, or say who appears on which version. It degenerated into simply stating a net worth figure for each sleb and then speculating what their deal was with Q.
Celebrity is such a devalued term, nowadays. If you look for a modern definition of a celebrity, you certainly wouldn't find any need for someone to have done anything noteworthy or valuable. Now you just have to be prepared to shamelessly make a complete a*** of yourself on TV (and soon on social media, I expect) to be deemed a celebrity.
You have a mixture of people who you've heard of and people you haven't (and could care less about), but at the end of the day when they go onto QVC they are only a salesperson. They just get better paid than most of the others.
Presumably QVC think it will shift more units of product than just a generic presenter, and if they don't they will be mercilessly replaced just as any other sub-standard salesperson would be.
Like in football, it seems to be all down to the "celebrity" having a super-sharp agent to negotiate the most favourable deal, for a limited period of time... to assure them of a nice contribution to the pension pot.
