Indeed, it's great to see that someone appears to have a good heart as well as an ample bank account. That large donation certainly has made a massive difference to the total.
(Just thought I'd add in here, that massive donation wasn't me. I wish I had that sort of money spare to donate, but I don't.)
It's very heartwarming to see so many people backing the beautiful lady in her endeavour to not only give this specific cause more exposure, but also taking such an active approach in order to raise some much needed funding for it.
There are many true stars about that tend to not just use their status and talent to achieve things for themselve's but also to help others. Natalie really is one of those that shine above so many others, but then I am quite biased, haha.
I've donated to a few different causes recently, my biggest regret is not being in a better position to donate much more. That said, I've done what I could currently and that's more than some can say who are in a better position than me.
It's brilliant to see that the total keeps creeping up almost every day too, there was a brief lull for a while, but since then things just seem to be keeping 'on-the-up'... So, it's all good 
Just in case Miss Imbruglia does happen to read these crazy ramblings...Well done lovely lady, best of luck with the event and I wish you all the strength/energy you could need to complete the challenge :)
Take care kind people.
