After the show, Hamiley had a chance to get her pictures taken with the R&B singer. However, it seems like the mother of four "messed up" the pictures big time. On Saturday, Govan made a post apologizing to her daughter for messing up the picture, resulting in a distorted picture. She also posted a video where the phone apparently fell from Govan's hands while taking a picture.
