I really like Iggy (or her label) for including Charli in all of the promo opportunities. It would be really easy to exclude her and it shows what kind of person Iggy is
Notice the part of the song thats actually used in the commercial
Obviously the hook which is the catchiest part of any song? LOL pressed hater Iggy already in a BIG commercial and Fancy making an IMPACT, like its 7 weeks at #1 were not enough.
