I'm confused on Kagami name I see Kakami sometimes and Kagami on others which is it

Well, I've read some comments that say the original kanji reads that it's pronounced 'Kakami', but listening to the drama cd, it sounds like they pronounce it as 'Kagami'... You can find the drama cd on Youtube, so have a listen and see what you think. (●'◡'●)ﾉ
