Who sings that song - it sounds like cover, remix of "My guy"?

I think lyrics are same as original by Mary Wells ( ...Nothing you can
do
could make me untrue......), but this is new song, sounds more like
Morcheeba, it's gentle female voice...

Aaargh, I dont' know, just heard it on radio but can't figure out
who's singing...
Help :) Thanks in advance
