I just don't know what to make of Tamara Ecclestone

I'm having a problem deciding what I think of Tamara (pictured here with her sister Petra on the right). She is doing some kind of a documentary about herself and her day to day life with Channel 5. And while it is a blatant piece of self-publicity which clearly shows her venal, shallow nature, there is also an intriguing other side which defies ready explanation. The film showed her setting up a charity auction for Great Ormond Street Hospital, than which there is surely no worthier cause. She also went out buying presents for the children and spent several thousand pounds at somewhere like Hamleys.
Now I am not such a naive cat as to believe her motives to be truly altruistic but the fact remains that were it not for her self publicity those sick kids would not have been in receipt of the toys at all. The same can be said of the auction itself. It apparently cost £500,000 to set up and only made £550,000. But that is £50,000 which the hospital would otherwise have been without and nobody said that Tamara was a brilliant business woman anyway.
I cannot leave the subject of the auction without mentioning that Alexandra Burke (a female pop artist) performed for no fee and made no diva like demands on Tamara's resources either.
So here is the puzzle then. Does it really matter if a worker for charity is vain, shallow and self obsessed as long as the work gets done? I'm beginning to think it does not.
The film also made it apparent that Tamara has a rather sad relationship with her father Bernie whom she quite obviously loves.
Her boyfriend (Omar) would seem little better than a hanger on who cannot be bothered to dress respectably when in her company. And he comes off considerably worse by comparison.
I think I shall continue watching the documentary with perhaps fewer cat calls and derisory remarks than I would have expected and I shall urge Old Nic to do the same.
