Celebrity related sites always pays very low, change your niche. But I don't mind getting your 63K view per day at all.
I think you need to check the placement and the blending. With such a huge traffic, you should make 3 figure income daily.
I saw a website that suggested about how Google calculate. CTR is used to calculate as well. So, it may be because of that.
It also depends on the niche and the keyword your are targeting. Just select the high-paying keyword to target so that the ads that will appear on your site are also high-paying.
