wedding song?

I was at a wedding last summer and they played this one song. It's not a very big song, but i know the singer is a younger local girl from Traverse City, Michigan. It's kind of a slower pop song. The only words i can remember are "cause you are my man, i will do all that i can...." not much help but if anyones ever heard of it some information would be great! Im positive its not "the power of love" by Celine dionne

i think it is by celine dion, i'm your lady
