**** is a light and informal way of saying " **in addition** " and it has the same kind of nuance as " **Oh, before I forget,** ~~".
Think of as a variant of , the sentence-ending particle.
You can say just without a sentence-ender in informal speech. Or rather, I should say that is not used in formal speech. In formal speech, you would use **** .
Seems to me like someone had mispronounced 's name and is now correcting it, but if that is not the case, please forget this comment.
