"So Help Me Girl" is a song written by Howard Perdew and Andy Spooner and recorded by American country music singer Joe Diffie.

[8] Larry Flick from Billboard gave the American version of "So Help Me Girl" a positive review, saying that it did not stray from Barlow's work in the group Take That.

"[9] A reviewer from Music Week rated it three out of five, adding that "the song's Nashville roots are barely discernible on this David Foster update which turns it into a swoony, low-key ballad to give Barlow another hit.

The second video, accompanying the American release of the single, begins with Barlow sitting alone on a bridge and throwing a rose into the water below, whilst a mysterious woman looks on.

The video continues with Barlow walking through a lighted tunnel of moving cars, before returning to the house and performing the final line of the song to the girl personally.
