Hilary Duff had a bit of a thong-tight moment whilst out on a shopping spree in L.A. yesterday.
The actress was trying on some jewellery when she had to pause to sort out her uncomfortable undies.
The star is currently finishing up filming on new movie Stay Cool, alongside Mark Polish, Winona Ryder, and Josh Holloway.
Hilary plays a high school senior who flirts with an author and tries to hook up with him at the prom.
