Jason Deulo's new lip-synch music video for his hit song "Talk Dirty" is star-studded!
In the video, Harry Styles, Niall Horan and Zayn Malik go shirtless while singing and dancing to the jam in their dressing room. The 1D guys ham it up for the camera while showing off their bodies. Liam Payne also shows up and, at one point, Horan hops around while wearing only underwear.
Also featured is Pete Wentz, who pretends to play the horn throughout the catchy chorus. Meanwhile, Grande gives the camera some seductive hair twirls while singing along.
The most hilarious celeb cameo comes in the form of Larry King, who recites several of the song's lyrics from behind a desk. "Talk dirty to me," the 80-year old says to the camera.
