I'm not even 100% sure of the title, but I believe it is "you are my shining star", but who is the artist?

Is this an old song? New song? Fast/slow??
Could be 'you are my shining star' by the manhattans or kim sozzi 'like a star'?

It could be by B5 or the one by Earth, Wind and Fire too.

Can you tell any more about the song?

I remember a song from a couple of years back called Star by Reamonn, maybe that's the one you're looking for?
