Here’s Colbie Caillat, whose version of this song has a definite article on it:
Did you know that Colbie Caillat’s father Ken co-produced Fleetwood Mac’s Rumors and Tusk? Well, now you do. Did you know that YouTube offers suggestions for other songs while you watch that video? One of the songs they suggested for me was that MILF song by Fergie. Make of that what you will.
Lacking a definite article for their Little Things is Ladyfinger:
I got that off an Amazon label sampler album a few years ago. YouTube did not offer me any song suggestion while I was watching it. Make of that what you will as well.
