In the video, which premiered exclusively on Tidal, Hadid puts her modeling skills to good use. Harris captured every sexy moment -- including her emerging from the pool in a teeny bikini -- and shared them on Twitter.
Hadid later does a little miming. Is she trying to get out of a box?
Another highlight from the video that Harris was eager to share was of the model dancing in a sexy midriff top.
While Swift didn't make mention of her 31-year-old boyfriend's music video release, she did call out Hadid's appearance in her own star-studded video for "Bad Blood" by sharing a behind-the-scenes clip on Tuesday.
In celebration of her bestie Karlie Kloss' 23rd birthday on Monday, the 25-year-old "Blank Space" singer shared an Instagram pic of the model hanging out in the kitchen with Harris. "Some of my best times are with her, laughing in the kitchen," she wrote. "Happy Birthday to the ray of light that is @karliekloss!"
