The singer confirmed on Tuesday that the video pays homage to four of her favourite movies after she dropped more photos, this time inspired by Legally Blonde , including a photo with the movie's co-star, Jennifer Coolidge. Once fans figured out that there was more to this video that meets the eye, they immediately went sleuthing to see if they could figure out the remaining films. And they did — almost. Grande confirmed that a photo of her new short hair posted on her Instagram Story was of her in character for the movie 13 Going On 30, but as for the fourth film, she's keeping her lips sealed.
