Ariana Grande burned her "butt cheek" shortly before filming a key scene in 'Wicked'.
The pop star - who is nominated for a Best Supporting Actress Oscar for her performance as Glinda in movie-musical 'Wicked' - has confessed she injured herself during her lunch break and needed to have ice packs applied to her behind while she was shooting the 'Defying Gravity' sequence with co-star Cynthia Erivo, who was also thrown off after her meal included her most-hated vegetable.
